G Body or A Body?

[Streetbu]

Technically an A body, but because the designation changed everyone refers to those years as a G body.

Never...EVER...forget this G-body... 😆

GM G body rarely known about Riviera by Buick

Few know that GM used the G body format so as to fit the shell of 1995-99 Riviera by Buick, the last of the G bodies.

The mid '90s Oldsmobile Aurora was also a G body, as it was produced on the same platform as the Riviera.

Granted that. But the point was more about poking a little fun at the phantom lurker who keeps posting up "rarest G-body" stuff.

Yes, I understand. I've read his posts as well.

OK.............now I'm going to throw a wrench into this! These pages are from the PONTIAC Parts Data Catalogue effective December 1979. Note that the A-body includes the LeMans, Grand LeMans, Grand Am, and Caballero. And............the Grand Prix is designated G-body. However, in 1979........and 1980, all the Grand Prix models are lumped together with the other A-bodies. I'm assuming some time after 1980, Pontiac sorted this out! LOL

The Grand Prix has always been listed as a G since '69. It had a longer wheel base than the other Pontiac A's up to '77 which was part of the reason (my theory) it was called a G. Pontiac didn't like the A-Special that was used with the Monte & '78-'81 A37 & A47 coupes.

From what I understand...all these cars were historically A-bodies 77 and before. GM knew they were making significant wholesale changes to the platform (and downsizing a bit) that they intended to quit calling them A-bodies with the roll out of the changes in 1978. But somewhere along the way, someone didn't do a good enough job communicating this on the corporate record keeping side of things. Therefore on paper they go down in the records as A-bodies, but there's no denying nothing about the platform really changed between 78-87. So honestly you're not wrong either way, except for whatever year it was 82/83 and up. Those were ONLY g-bodies

I did find this in my 82 book and did notice that they made changes to all the Vin's for 82.

This proves that it was still called a G for the Grand Prix in 78.
