first off its a 93 z32 TT, okay my passenger side window goes all the way up but doesnt stay tight to the door frame, i found that the part that holds it is gone......when you look at your window, when its up the part is that place plactic dot in the center of the window all the way towards the back, it pulls the window in by attaching to that little slit you see when your windows down, this is really hard to explain so i hope someone understands......anyways i want to know if i can replace it for if i have to buy a who new glass assembly for the passenger side.....??????
