I did not, in fact swap my nose from square to round. I just swapped the nose 2 times!
But the chassis is the same, and the monkey is right. You only need the hood, fenders, grille assy, headlight buckets, bumper(if ya want) and maby the lower roll pan!
But it is a bolt on plug and play swap!
Doing a 510 nose on it, Im not sure would be that easy... What year 510? Theres a possibility that the 78 and newer-ish 510 nose would fit kinda?
