As I was installing AWR 70A motor mounts to my BP5A swap, I only thought it appropriate to change the differential bushings as well. I ordered a set of Garage Star delrin diff bushings and went to town removing the stock ones. A little heat and a few whacks of a chisel and they were out. I froze the delrin overnight, but found that was really unnecessary, as the bushings slid in and out even after installation.
After raising the diff back up, I reinstalled the lower plates as directed, but even after being torqued to as far as my 3' breaker bar could go, the rubber fingers still were about 0.5" away from the bottom of the diff. Try as I might, I could not tighten the bolts down far enough to contact the diff.
After driving the car this way for a few days, I noticed the differential clunks and shudders a lot. I got under the car and checked the diff only to find that a pry bar can move the diff up and down about 0.5", the free travel between the diff case and the lower mount cap rubber.
I have since tried to contact Garage Star and gotten no response, and would not buy these again as they do not fit and apparently no product support.
I have ordered another set of bushings from another company and hopefully have better results.

I can't say i have read too many people installing them but i doubt Ken would keep making them if they didn't sell. :dunno: Best (?) case scenario you got a flawed set. When/if you hear back from Ken maybe he can provide measurement specs to check yours against. How long has it been since you emailed Ken? I know most companies have a pretty hectic schedule at the end of the year so he might be stretched thin.
