Map light, trunk light and reverse light

Ok, there's a good idea. It's a 70 Duster.

Map light I've figured out the map light.

Trunk light I've found 1 picture of a car with the trunk open and the light lit up near the DS trunk lid hinge. I don't see any pre-drilled holes for the light itself. I know where the switch is mounted.

Reverse light. I'd really like to see a close up picture of that. I don't see any holes in the dash where it may be mounted. It's for my son's car and he has a set of after market gauges to mount, but I don't want them in the way of factory stuff.

Thanks
