Exactly. The engine mounts are absolutely good and I just checked the CB here very recently and I don't do hard take offs like drag strip stuff so the chances of that thing getting wasted between the time I checked it and now is HIGHLY unlikely, especially since I checked it within the last 3-5K miles. The only thing that leaves is the trans mount and the diff. To answer your first question though, yeah, it sounds like it's coming from the rear. I give it some throttle when backing up, and if it's anything more than a gentle feather I feel this THUMP feeling.
The fact that no one offers a poly trans mount for these cars yet is mind numbing considering that they offer poly crap for literally everything else around the car.
