I had to replace my rear 1/4's window motors. The POS place put the glass in wrong! It stayed that way for maybe 1-2 years. I could roll it done enough so it would be right. When my conv top opened on its own, I added that to the list that needed to be corrected! They were just about 1/4" too might, I;m guessing. I took it to the losers who f'd it up. They said it was just fine. Every time it would get wet, it seeps water in though. It's perfect now though! Has it always been too high? Or did it just start being this way? I cannot answer either question, just thought it might help the others.
