Right now I'm in the process of redoing my doors, the car was re-painted a little over a year ago and the rust repair on the door botoms wasnt done, now I have the experience and knowledge to do the work my self, I found some door skin bottoms that will work great. anyways........Does anyone know if GM or anyone else makes and replacement parts for the window regulator assembly? My doors are stripped out totally and I figured now is the time to replace this stuff, any links or info would be great. Thanks guys
