the one on the left with the plastic piece attached to it fell out from the middle of the window when I unbolted one of the regulator bolts. The regulator obviously had been out before because there were no rivots. I have looked at an exploded view of the regulator setup and cant find either of those pieces in there. I am thinking that maybe the round one is a metal bushing. from what i understand, there is either a metal or plastic bushing that determines how the teeth on the reg meet up with the motor gear.
like I said, I am new to this car, and havent really had a chance to tear it up yet.
so you are saying then that neither of those pieces are needed as far as you know? I am pretty sure that the front regulator assembly is the same on all e36 models. I know the backs are very different on the verts.
