I thought I'd be smart and skip ahead to locate the door strut brackets to the canopy before I mounted the OHC which would make access problematic. Plus it would allow me to locate where I'll need to make cutouts in the OHC for the brackets to fit. I then compelted drilling holes in the OHC for the reading lights, switches, and eyeball vents. The light and switch holes were drillled with a step bit. I used my Dremel to cut the much larger vent holes.
