Third light

[Squirel]

I'd like to add the third light to my 1991 GMC sbrc, is it possible, has it been done?

The light over the rear window.

If you want to use an OEM one from 1994-up go find one in good shape first, regular & crew cab use one design, extended cab uses another and they do not swap, different roof profile where it curves down towards the glass. Get the harness that goes to it. When you take the light off the truck you'll see the 3 big holes in the roof that they make for it to fit...easy to make a paper template from that. Could be a little tricky doing a clean job of cutting that into your truck, so plan carefully..
