My driver window never went all the way down and seemed to have a lot of play on the back side. I pulled the window and regulator out and checked everything. The only problem obvious was that the rear window track was off.
I put it back together, this time with all 3 tracks connected, and the alignment was way off. It now tilted forward about 20*. After scratching my head for a while it dawned on me that the window may have been intentionally left off the track to get it to go all the way up.
Ive found through some searches that their was a different window for 240, 260 and 280 z's, but also read something about possibly having a door from a different model car as well. Is their any way tell which window I need. In one thread zcar had mentioned cataloging the differences but nothing shows up.
