1998 Chevy Monte Carlo power windows

do not know exactly about your make and model, but I had to drill out the pop rivets, then it was a little tricky moving it around and getting it out. I did not have to re-rivet it in, however, for i drilled the holes for mounting in the new moter out just a lttle, and found short 1/4 inch nuts and bolts to reinstall, i also used the nylon nuts.

I was afraid of that, I may do all the tedious stuff and let my repair guy do the motor,, but I may go for it..... appreciate your feedback
