Window motors, 1992 Ram

I have done that with mercury grand marquis and ford crown vic square bodys. Theres 3 dimples in the sheetmetal structure behind the door panel to drill access holes. Factory doesnt punch them. I use my 3/4" rotabroach hole cutter, and viola the bolts are right behind there. Maybe your ram has similar dimpled spots in the inner structure right where you have to drill with a holesaw to access the hardware.
