Body to Frame Mounts - What's the Joke Here?
« on: June 18, 2011, 06:59:00 PM »
I've noticed that W187 sedan and cabrios have different mounting plates between the frame and the body. But why?

OK, the Cab A body has a wood frame, but the Sedan and Cab B should be quite identical by both frame (excl. extra support welding in the middle) and body floor. So why do they have different height and different material (rubber vs. aluminum) bushings? See attached picture (blue dots) for what I mean.

I can come up with three theories:
a) the height
b) the Cab bodies need to sit stiffer to the frame (for some reason)
c) the frame and body floor is totally different (unlikely, since all measurements and structural parts match).

But why then?


EDIT: OK, sorry, one of the blue dots is in the wrong place, but you get the general idea.  ;)

I'm pretty sure that is was to mitigate drumming in the sedan bodies. The Cab B wouldn't drum because of the soft top. As you said, they also may have wanted as much rigidity in the mounts of the convertibles to keep body alignments.
