Cant be as bad as a firebird, they are RIVITED in. Good luck not destroying the inner door as its soft like cardboard or some fiber. Then try to not slip and break the glass. Then as you use the window with the new motor it just tears down into the door more and won't seal right then, you end up using lots of jb weld and washers and nyloc lock nuts. I feel bad for the next poor bastard to have to change it.
