If you want to use the '67 Shelby Style taillight panel with the '67-'68 Cougar lights, you have some more parts to buy and some cutting to do. On the '67 Shelby’s, there is a large rectangular section that needs cut out of the taillight panel for each light housing. This is because '67' lights sit more flush than '68's. You'll have to get someone with a '67 Shelby or clone to measure the holes and location for you. There are steel boxes that rivet to the taillight panel in the trunk area that cover the holes (you may be able to use these as a template for the rectangular hole on each side). The taillight housings then bolt to the boxes, and then the lenses and trim bolt on. It is kind of a crude set up. The '68 set up would be much easier for you to install since the taillight buckets bolt to the fiberglass taillight panel and then the panel just screws to the metal taillight panel. If you really want the '67 style, you have some crafting ahead of you. Go to
