Got any pictures? I would like to see it.I put one in from a late 90's/early 2000's silverado. It was much longer than the one in your picture. The aft edge has a bracket which I slid into my existing dome light cutout, then I used a tinnerman nut above the headliner to accept the forward screw which holds it in place. Only cutting that had to be done was the hole (#21 drill bit) for the forward attach.
