As some of you might know, I've been messin' around tryin' to get a line of polyurethane parts goin' and the first piece was a differential mount. Well, between all the SC stuff I try to accomplish and the gf and the cats and the house and day to day life I actually took the time to work on my own car. Yep, no kiddin'!
I had access to a friend's lift so I put my '94 5spd in the air to finally do the diff mount swap, found a surprise along the way. The batch of pics below will tell most of the story but here's a few details.
First thing I noticed was the top layer of rubber in the center of the original mount had been grazing the subframe. Mount isn't busted but was evidently flexing enuff to rub every now and then.
Second thing was the drastic difference in metal thickness of the late mount compared to the early mount. The early mount I installed is easily twice the thickness of the later version so I felt good about puttin' in a somewhat heavier duty part.
Moral of the story...even if you replace the diff mount on your 94-up with one from a partshouse (instead of one of mine) ya might wanna look into specifying that you want one for say an '89 or '90. By the way, I don't know what year the thinner mounts might've been phased into use as far as the break point concerning year of car. Any info on this would be appreciated.
I still have sloppy upper control arm bushings so the wheelhop is still present but feel much better not only because of my "new" mount being polyurethane but also because it's made out of thicker metal.

Closeup of where the old mount was rubbin' on the subframe due to flexing under torque.
Coupla side by side comparison shots. Late mount looks kinda dinky doesn't it?
Old rubber mount on its way out, new polyurethane mount installed.
