if you already have the door panel off, you are 10 minutes away from having it done.
there are 4 screws holding the regulator to the door, 2 screws holding the window to the regulator, and 3 screws mounting the motor to the regulator.
there are also a couple or so holding the motor bracket to the door.
10mm socket and a #3 philips head is all you should need.

I don't recommend used on a window regulator.
there are aftermarket ones out there at reasonable prices:
