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.
