Had one sitting around for a long time and forget where I picked it up
I plan on using it on my build and you can see how I will be installing it (post #115)
http://67-72chevytrucks.com/vboard/s...=318544&page=5 I lined it up with the visor bracket holes and used cleckos to hold it in place, working from the center out. You have to be careful drilling the holes not to drill to deep or you’ll hit the outside skin with the drill. Also drilled a one inch hole behind the outboard speaker pocket to run the wires thru a grommet.
