You need the power window regulators. They are very different, as the window motor bolts on to them from inside the door. If you really want to do this, you will need both of the regulators, the door wiring, all the wiring between the doors with the rubber door boots, new door panels, new arm rests and switches, and probably power locks if you don't already have them. All the PW armrests already have PL switches.
I did the change since I got a mint GT interior for my LX that had PW & PL door panels. It was not hard, just took some time drilling out rivets and running the wires. It hooks to the power with two wires in one plug by the fuse box. You would also need a circuit breaker for the fuse box to power the stock wiring.
If yoou remove a power regulator from a donor car, be careful since it is spring loaded to help the window go up. I almost pinched my fingers on mine! Use a long bolt, nut and washer to hold the spring loaded regulator in place when installing it. Or maybe a screwdriver.
Good luck!
