Just the one you show in your photo from the parts book. As I recall the motor section is forward and the upper arm front screw is near the door opening sort of under the window pivot while the length spans the access opening to the rear hole about in the middle. A third screw is at the bottom of the opening Like the front doors, a bar connects the motor section to the second half which mounts with two screws sort of in the middle with the track for the end of the window actuating arm to slide in welded to the inner sheetmetal closer to the wheel well.

There is very little spring assist or any decent mechanical advantage in the regulator to lift the heavy glass so the motor is straining to raise the window. I do not know how the replacement motors will work in this situation. One thing that helps is take care to center and align the window with the upper fuzzy channel and use a grease that won't dry or get sticky to lube anything that slides or moves.
