The early ('84) 190Ds used a mount similar to the solid mounts used for
123s.
Yeah, that's what they look like.
They don't fail gradually. It's a binary function. When the height
drops
below 1/2" the isolation has become unsatisfactory. If you use a mount
from a different engine/transmission combination, the isolation will
NOT
be satisfactory whether the mount is good or bad. Quite unlike solid
mounts used in older designs.
That's too bad. I still may try it, I doubt it could be worse than
it is right now. And if it's better, cool.
