I have a 1986 Pontiac Bonneville 4 door and the frame is rotted away. I was wondering what gbody frames would interchange with no major modifications.

1984-1987 Cutlass 4 door should be a direct swap. Not sure how late they built the 4 door Buick Century, but it should swap too. Most 4 door A/G body frames from 1981 should work. The only thing you might need to watch for, is the frame rail extension on the left side, to allow the transmission crossmember to mount further back, for the 200R4 transmission.
