I have the mechanism and electricals, I need the motors for all 4 windows. I have seen
I. A1 Cardone brand remanufactured units (which look like the originals), but come without the gear and "regulator" (whatever that is).
II. Replacement and Dorman brands new replacement-style. These look different than the originals, but look like they have a bolt on. These come with the gears.

Anyone have experience
