All non-U.S. Mangustas for all years were four headlight cars; only the U.S. destined 1970-71 cars got single headlights and maybe not all of them. Don't know what the fender & grille differences were (if any) for the two styles.
I've never seen a Mangusta build sheet, and the 'Goose Parts List does not mention all possible parts and is in Italian- some hand-written. Good luck.
