One of the round cylindrical parts (2- one on either side) that drive the california roof forward and back and lock the roof in front has come loose on my 1996ti. The parts i'm describing look like the winch on a sailboat and are secured in place by torx cap screws. These are the vertical posts that ride in the right and left roof channels and move when the motor runs, they also click into the c-shaped rubber clips at the front of the cloth roof support structure and bump into the limiters at the very front of the roof channels. Anyway, the stack of 'bushings' are vaguely referred to as "Fulcrum Pads" in the TIS bulletin on California top removal & reinstallation but there is not a photo. I have looked and can't find any part numbers on part diagrams like real oem. I've searched the other posts on 318ti.org and the only other post I've found references them as "drive pulleys" and "drive posts." They appear simple enough, and the whole stack is held onto the post by a tiny doughnut like washer that is held captive by the tiny torx screw.
Does anyone know what the heck these things are called? How about a part number? Any tips on fixing this thing? I'd like to use factory parts, but I fear I may be headed to Home Depot for a really tiny flat washer or c-clip. Would be nice to replace both of them while I'm at it since the other one is likely not far behind. Any tips? I attached links to photos, hopefully they are visible below Thanks! -Frazier
