I have been told by members of a social group devoted to 1973-77 A-Body "colonnade"-style that the new 1977 downsized B-body (Caprice, Bonneville, 88, and Le Sabre) was no more than an A- body frame with a new body bolted onto it.
Is this true???

I don't think so.
What several members of the "Colonnade" group said was that in order to downsize the full-size Caprice, Bonnie, Delta 88 for
1977 they just built those on the existing A-body, which had a 115" wheelbase vs the 120"+ wheelbase of the outgoing B- bodies.To downsize the A-bodies(Monte Carlo, Grand Prix, Cutlass, et al) for 1978 model year, they created a new 110" wheelbase platform.
Just looking for some validation on that first phase, because while I understand that reusing existing platforms can save money for an automotive behemoth like GM, it suggests that "all new for 19- so-&-so" may be a bit deceptive marketing to buyers.
