I have a 67 GS vert. When i purchased the car the right rear (Power Window) regulator was missing the gear that goes on the electric motor. After some research I have found out that the rear Power window regulator on a (convertible only) has a larger gear that goes on the motor and engages the window regulator. Does anybody have a convertible parts car out there or a regulartor for a convertible. I am not sure if i must stick with a 66, 67 style or the gear from any gm convertible from that era will work. I am willing to trade parts or pay cash for this piece. This car is really nice and deserves to be complete. Thanks Scott
