That'll be quite a list. I'll take a stab at US version cars:

81-85 300SD
86-87 300SDL
90-91 350SD/L
81-85 380SE/L
88-91 300SE/L
86-91 420SEL
84-85 500SEL
86-91 560SEL

There are also non US variants such as:

80-? 280S/E/L
85-? 260SE
other years and wheelbase lengths of models in the US list.

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... ).
