Grab the regulators w/motors, wiring, relay, armrests, switches, door panels, and any nuts, bolts, & clips that are used to hold the regulator to the window.

This site should help with the procedure:

At one point I planned to do this, but I never got around to it. Therefore I have all the parts for the swap if anyone is interested in buying them as a complete "kit."

it is 100% do-able. 240s are built for assembly line ease.

If you have the patience, every bit can be removed and put in your car.

You CAN swap in the door panels, too.

I think the window 'carrier' and linkage is different for power windows than for manual, although I know there was a dealer-installed kit which basically replaced the crank (and switches were in the dash). If it's easy enough to do, just grab the whole window assembly, glass and all. You'll have to get power lines thru the door jambs, but beyond that it should be all pretty much bolt-on. You'll need the door handles to mount the switches, too.

The power window harnesses are all seperate from the rest of the wiring. With a little time and care you can pull everything out and put it in your '87. You will have to plug the holes in the door for the old cranks and do some modification to the door panels to mount the power window armrests. Time consuming but doable. As to the power mirrors that's an easy changeover if the '91 has them, I put heated power mirrors out of a '93 in my '88, took about 1 hour total, can't help with any information on Saab or other replacements.

Hmmm...wondering about this myself. I've got an 88 245 that could use a little powering up too.

So let's help me...er...GMoney out and give with some experiences, huh? ;-)
