Rear window track replacement.
I would highly recommend A-1 Auto. I watched the video your company provided on line before I ordered and while I was waiting for the delivery. Never removed any door panels etc, however it went really smooth thanks to the on line video. Only one issue I ran into. The track was in the up position and I could not line up the studs with the holes. Fortunately my wife had me run the track to the lowest position and it fit right in. (she used to work on our chevelles with me and is mechanically savvy) I would have given 5 stars if not for this little glitch. If it was in the video to have the window track in the lower position and I just missed it then please add the 5th star. Thanks again for your on line video and free shipping.

High Quality part
I ordered a rear window regulator for my 2000 Buick Lesabre custom PGA Touring Edition, and I couldnt be happier with my purchase. It arrived exactly when they said it would, and it was a very high quality part. I will continue to use 1A Auto parts for all of my repair and replacement needs for both of my vehicles. Josh J.
