Hi ,
I guess you are going totally race, huh? You wouldn't want to transfer the power window stuff, etc. Let me give you some advice via experiece. 4th generation camaros and firebirds have plastic doors, and I had total nightmares when I replaced a driver's side window motor. I drilled out the rivets and bolted the unit back in, but adjustment was another thing. When I finally got it right,two weeks later the car was back with a jammed window. These are factory doors, so GOOD LUCK with that aftermarket stuff. Maybe you have some skills I lack, but you will have fun, rest assured!
