I have a set of '70 doors that I'm putting on my '69 Mach 1. These doors don't have the holes around the hinge area for the courtesy light wiring to pass through. I need to drill these holes, but I don't have the original courtesy light wiring harness or the grommet that would tell me what size hole to drill.
I'm assuming that the door grommet is the same size as the one that goes through under the A-pillar, which is, if I remember correctly, 1 3/4th inch. However, I'd hate to break out the hole saw and put the wrong size hole in the doors. Can someone verify how big the holes in the doors should be? Thanks!
