Does anyone know how hard it is to install power windows, or would I come out better having someone else do it for me ???
Reason for asking, I got someone willing to install them in my 89camaro for $350, but its an aftermarket kit, and another guy says $650 for the authentic Camaro kit.
Which would you guys recommend ???

Theoretically all you have to do is swap the regulators in the doors to power window regulators, bolt in the motors, cut holes in the console and run the wiring. The switches are $11 each new for a camaro, and the motors run about $20 each from any discount parts store. No point in reusing used ones when they're that cheap.

You should be able to find a pair of regulators and all the wiring for less then the price you were quoted.

I've got a set of doors with power regulators, all the uncut wiring from the doors to the center console for sale. PM me an offer if you're interested.
