MGB Interior Panels - Part 2

Today, I continue on Oliver's (the MGB) interior because the weather remained a preventative from getting to the cars outside. Darn, have to work in the semi-heated garage.

High-Level Door Card

black door now out of place

By now, the door cards were looking completely out of place, as the only remaining all-black panels. These are a little more complicated than the front kick and rear quarter panels. First, there is a top padded section which holds the top of the door card in place. The padded section is held on by 4 screws (2 each front and rear) and is wrapped with black vinyl. The interior kit delivers with a section of cream-colored vinyl to replace it. Additionally complicating things, there are the window crank, and the door latch pull and lock. In my case, I removed the armrests shortly after buying Oliver, but there is the old blown speaker. Last, each door card is held to the door with 13 plastic clips. Since these are original 1978 plastic, I suggest having replacements on hand. The interior kit did not include these, but they are, like $0.50 each or less online.

 

I didn't take a picture of the driver card before I started, so here's a picture of the passenger side, from the open driver door. I leave that towel on the driver seat so I don't accidentally get grease or anything on there while I work on him. You may also notice I have omitted the center console. I think the interior looks less complicated this way and the console acts like a little wall between the driver and passenger, which neither Boo nor I liked. Either way, there's no place to put a beverage. I may solve for that one day.

 

Padded Section Reuse

after polishing

I considered re-covering the padded section along the top, but after removing it (4 Phillips screws), I decided not to. First, the wood inside the padding is starting to fail (see picture below). It's not totally bad, but bad enough to warrant replacing eventually. I figured that if I used the cream on that now, I would not have it when I replaced the wood. Second, the black vinyl, while also not perfect, could get cleaned up with some leather cleaner. Last, I already had a cream and black contracting interior so retaining the black long the top would help underscore that. Ultimately, I believe retaining the black just for that contrast reason was plenty of justification. I think it looks really good.

So, I cleaned the rust off the chrome ends with some Goof-Off, and polished the vinyl with leather cleaner. The window felt was fairly worm out, so I removed it with a slotted screw-driver. Rather than use a staple gun to install the new one, I used 5/8 inch #18 brads. When installing these, you will notice that the chrome/felt does not go all the way from the front rubber seal (sealing the flip-out window) to the rear-most point on the window. I taped the felt to the padded section with painter tape and held the unit against the door, shifting the felt side to side until it was where I liked it. Then, I sent half a dozen brads in to hold it firm.

 

Removing Rusted On Window Crank

As easy as it was to remove the padded section, removing the window crank was the opposite. The Phillips head screw had fully rusted to the mechanism. I applied Kroil and let it set, but it couldn't effectively penetrate past the window crank. I had to resort to my set of "easy out's". I find these are neither easy, nor do they really get the stuck bolt out (could be user-error), but in this case they did what I needed. After stepping up the drill bit size a few times, the head of the bolt fell off and the window crank handle could be removed. Once out of the way, I just needed to pull the plastic retainers from around the door handle and the door card came right off. I removed the remainder of the bolt from the window crank with a big set of lock-pliers. While I had the Kroil in-hand, I lubricated the various moving parts of the window: the window control joints and the spring. Surprisingly, this reduced some of the clank-clank-clank noise when the window is raised and lowered.

 

Outer Scraper

torn down

The last bit of demo was removing the old outer scraper. This is that supposed-to-be pliable rubber that presses against the outside of your window, stripping off water, mist or fog when you roll down the window. More importantly, it reduces rain water from running to trickling into your door. My scrapers were hard and chipped, so they needed replacing. They are held to the inside of the door with 7 rivets. I set a slotted screw-driver blade against the rivet and smacked the handle with a hammer. The rivets pop right off, but the bits fall inside your door. Once free, the new scraper lines right up with the original holes, though on the very end there are a few different mounting holes, probably for use on different models. I needed to open the holes a little bit with a rat-tail file in order for the new rivet to easily fit through.

To mount, I set all of the rivets through the scraper and loosely set them into the holes in the door. With my riveter, I started on the ends, working my way towards the center. With each rivet, I would make sure that the rubber set up on top of the door, and did not disappear underneath / inside. I found that I had to press the riveter and the scraper hard against the door when pulling the trigger. With the scraper riveted in place, I checked the window action.

 

Noise Muffler

window crank and spring

With the scraper in, I cleaned up the inside of the door first with the shop-vac and then with spray cleaner. With the door cavity relatively clean, I applied some noise deadener. I realize this is a convertible, so there will always be noise. The door application is really about making the door sound solid when it closes rather than tiny and clanky. It doesn't take much to make a difference. I have read that as little as 50% steel coverage is sufficient. I am not sure I even got that much covered, though the door has a satisfying, solid "chunk" when it closes now. I ran a 4-inch tall strip from the outer rear view mirror to the door handle above the belt line (inside the door cavity, of course, but against the outer skin). Below, there are 2 front-to-back channels to which I applied 1-inch strips from the window regulator to the rear edge of the window. Below the channels, I applied a rectangle along the lower rear section. I found that the spring clank-clank-clank could be felt most on the steel directly beneath it on the inner skin, so I put a 4-inch square inside the door cavity on that section of steel. All sections were pressed down with the little roller application tool for a solid bond.

 

Plastic Sheeting

Originally, these doors had a vapor barrier. This door, however, did not, except for the small sections around the door handle and window crank. So, I made one out of a kitchen garbage bag. If I had thicker-mil plastic, I would have used that, but these bags are hard to cut, so I don't expect this to fail. I cut the bag so I could completely cover the door, and taped it in place with painter tape. With a Sharpie, I marked where I wanted the vapor barrier and then cut along the line. Since my furnace is in my garage, my options for adhesive were limited. I would have used spray adhesive or the brush-able epoxy, but both need ventilation and are explosive hazards. So, instead, I used Elmers Wood Glue. Yes, that's right: wood glue. It took longer to dry, but it held the plastic firm during the panel install. While it dried, I cut holes for the door latch and the window crank. I have found that applying adhesive on vertical angles creates a path for water droplets to follow if/when it gets between the plastic and the steel. On other words, don't apply adhesive straight across: it will only trap moisture against the door.

Panel Install

home-made vapor barrier

I could feel the end approaching. With the holes cut in the sheet, it was time to prepare the panel with the 13 clips. The card has 13 very obvious spots for the clips. They are shaped like a classic 2-ball snowman: large circle on top of a smaller circle. The clip slips into the larger circle and is then pressed into the smaller one. I could have re-used some of the clips from the original door, but after over 40 years, I was not sure they would not break during install, or shortly thereafter. With the clips in, the hole for the window crank needs to be cut next. Similar to the rear-quarter panels, the door card shows exactly where the hole needs to be. Unlike the holes for the rear quarter panel, though, the window crank hole needs to be cut almost all the way out to the hard-board edged circle. Also, the leather/vinyl has a padded backing that needs to be cut through.

I decided to not include the arm rest / door pull and I am not putting speakers back into the doors so this one hole was the only one I needed to cut. This greatly simplifies the look of the door card (see picture below), and even with the extra bounce from the thicker card, I can pull the door firmly shut simply from pulling on the padded section. The card did arrive with indications for both the arm rest and the speaker mounting locations, though.

With the hole cut and the clips in, I was ready to press it in. I started by aligning the bottom clips with the holes along the bottom of the door. Then, I clicked in the clip nearest the rear view mirror and then worked my way around, snapping the card into place. I trimmed and cleaned up the hole for the window crank (I had cut too conservatively beforehand) and then installed the crank. I again tested the window action.

Padded Section Install

so pretty

Last, the padded top goes back on. The new cards are more stiff and thicker than the ones that were just removed. It will be some time before these new cards settle in, and the original screws for the padded section were not long enough to bridge the gap, initially. So, I found a screw in my drawers that matched the thickness of the original screws, but was about 3/4-inch long. I set it aside for a moment and attached the front-edge of the padded section with the original (smaller pair) screws. I left them plenty loose so I could adjust and then grabbed that long screw. I sent it through the lower of the 2 holes in the rear mount and tightened until I could send one of the original rear screws into the door and have it grab. I checked the alignment and then snugged that original bolt. I pulled the long screw and sent the other original rear screw in. Last, I tightened the front mount screws.

Feeling quite satisfied, I shut the door... and it bounced back open. Ah yes, the cards are thicker. I closed the door hard and it held. I figure it will take some time for the rubber in the weather-seal and the door card to come to terms with one another. To help speed that, I will leave the door shut tight. Of course, the not-dry-nor-warm weather outside will help that door stay shut for a while.

Well, that's it for today. I need to do the other door, of course, but with the passenger door so close to the shelves in the garage, it will wait. Until then, well, I'll have to find other things to fix on the fleet. Like the clutch on Gramps, the rear wheel bearings on Nemo or maybe something I haven't discovered yet. We will see. As always, thanks for following along-

surround bits

UPDATE: I did the passenger door this past weekend (5-June), following these instructions. I had 2 additional observations. First, the replacement inner door felt scraper is about 1/2" shorter than the original. The missing 1/2" on my original did not have any felt left, and it was the section closest to the door handle, up against the chrome end. Second, I omitted the last step in the instruction above regarding the 2-piece plastic rounded-cornered rectangle that goes around the inner door pull. These are thin, and could be damaged upon removal. Fortunately, my old vinyl cards were not holding on too tightly, and they removed with ease. The top part slid right off, simply by pulling up. Once removed, the bottom came out easily.

Installing the Plastic Inner Door Pull Surround

I found the install to be much more difficult. The new vinyl has much more grip than the old vinyl. Also, the card wants to be flat, so there is natural pressure away from the curvature of the door. The plastic bits had 4 little bumps (one on each short side and 2 along the longer side) that need to get under the door pull. After multiple failed attempts, I found success. Starting with the bottom piece, I got the plastic wet. I set the 2 short sides on either side, below the pull, and while pressing against the card with one hand, pressed upwards on the corresponding corner of the surround. I moved from side to side, moving it a little at a time until the bottom edge clicked in.

halfway there

The top piece was harder to manage, in part because my card has a piping strip that runs right along the spot where the plastic bit needs to sit in order to install it using the same method. So, again, I got it wet (reducing friction) and rather than start at the uppermost corner, I lowered the plastic piece so it was just below the piping, with the leading edges on either side of the surround. This placed pressure on the piece, and this is where an original piece could break. With one hand pushing the card against the door, I pressed the little bump under the inner door pull. This was a little scary, but once the second side snapped in, I followed a similar effort of sliding it down a little bit at a time on either side. Eventually, the top and bottom pieces meet, and the cards are complete.

Again, thanks for following along. I hope this last bit helps you out. I found following these instructions really helped me out when I went after the second door.
