Pinion and mounting are the 2 difficult parts as you know-and the pinion being the more difficult. I cannot tell much about the pinion from pictures. Modern windowlift and for that matter all auto electric motors are permanent magnet-no field coils. Reversing is achieved by reversing polarity on the armature which is easy to achieve-the controls may not look like the orginal? I have assumed Packard used an arm/sector system? GM in later years used a tape drive
