you "could" get a ticket for no side markers "blinkers" if you put the quad headlight header on the pre 82 if you dont change the fenders.(82 and newer have blinkers down low) You have to grind down 2 small fiberglass pin looking gadgets on the header panel. You could use the same core support, you just need to get the air saw out, and cut the area for the headlight buckets to protrude through. As mentioned, the wire harness needs changing.
