Will a 77 regal two door fit on a 76 regal two door?

Well, honey, technically speaking, the 1977 Buick Regal two-door should fit on a 1976 Buick Regal two-door, as they are both from the same generation and have similar body styles. However, there may be slight differences in measurements and mounting points, so it's always best to double-check with a mechanic or body shop to ensure a proper fit. Good luck with your vintage car shenanigans!
