The steering on these little British cars is only a hair more complicated than the old VW bus. The bus uses a system called "work and peg", which is definitely not used in modern cars. Without opening up the steering box, consider that there is magic inside this box with two arms coming out it. The arm coming out the top connects to your steering wheel and the arm coming out the back connects to control arms that terminate at each of the front wheels. Within the magic box live the worm and peg. The "peg" rides on the "worm" that is a threaded bar that looks like an auger. As the steering moves from lock to lock, the worm moves the peg from side to side, causing the front wheels to turn. Simple design.
Getting It Out

In order to easily get to the rack bolts, you may need to remove the little section of cowling between the radiator and the front beam. It is made of glueboard and held on with a couple of nuts. There are metal replacements for the cowling available, if your original is trashed. Once you have access to the rack, it is held on with 4 long-ish bolts. With those bolts removed, the rack can be removed by pulling it forward and down. If it isn't budging, check that the steering column is loosened enough.

The OEM part, as expected, looked perfect and fit as you would expect. I threaded it on to the marks and tightened it down.
I am finishing up some other tasks before re-installing the rack, so I will post again when I have that completed. Thanks, as always, for following along.
