Look in the catalog tab at the top of the page. search for 87 420SEL and your yr 300D for rear brake Rotors and rear Calipers. that is what I did to come up with the info I posted.

Maybe one set of calipers are Bendix and the other are ATE?

Mercedes use the rear Rotors for well over 20 yrs on various chassis models,
w114/115, w116, w123, w126 and maybe more.

The Calipers are the same between the 123 and 126.
