Copilot... isn't it amazing every post always gets sideways from what the Poster askes? Well, yes I have a 73 that i finally was successful in fitting additional tail/brake lens to the inner bezel. Well.... half a lens,lol. See ifn yall can visual this. Took a reverse lens and a tail lens, bandsawed them in half, lengthwise, mated and plastic glued together. Even tho they're slightly different shapes they can mate to seal watertight which I did in and out. repaint the surround black band and the reverse half screws back into its place. the outer lens half barely fits the recess but looks natural. Rewire, stow the reverse circuit, tap into tail and brakelamp circuits, had to replace hazard flasher with HD unit. Its baddazz.
