Yeah, not that simple. Mustang lenses must be thicker, sockets were hitting valance so had to modify my socket holes, I didn't think the lenses would survive the belt sander with all the perimeter breaks. Once I had the housings exactly where I wanted them I Gorilla taped them in place. Free hand drilling the mounting screw holes was not fun but it worked. Cut down the weld nuts and got them welded in. 67/69 reverse lights on my 68 is now finished. Back to electrical tomorrow since my dealer only front 2014 Chally turn signal pigtails are in. $100 for both. Jeezuz,Weird, NAPA had the headlight pigtails for $18 a pc. That's Hot Rodding I guess.
