That'll be quite a list. I'll take a stab at US version cars:
There are also non US variants such as:

Basically any mirror for a W126 will work. You probably want to keep the remote adjustment function. If you want heated mirrors you'll have to stick to the 500 and 560, I think. I don't know if you can use a heated mirror if you don't have the connections for it.
I don't know if the finish is different between years and models. I don't know if all are convex (objects in the mirror... ).
