The '78-'80 have just a plan curved contour compared to the '81-'88 styled contour. With some skills with some dollies & hammers one can make fairly nice patch panel to repair. Bad thing about the '78-'80 Monte Carlo's will be the limited restoration support. Other than the panels shared across the '78 up A/G bodies there's nothing for your year. Maybe some fiberglass go fast panels but that'll be it.
