Well, I added a '75 Buick LeSabre ragtop to my formerly all-Pontiac stable (67 Bird, 66 Goat; I'm buying bigger as I get older it seems). Floor's been jury-rig patched with flat sheetmetal and poprivets in one of the 4 footwells, but another footwell is pretty bad as well. I found an Arizona floor pan that's over a grand with shipping, so I'm going to look around here (say 50-100 mile radius around Philly) in case I can do better. After wire wheeling, I find that some of the floor (and the trunk) only has minor perforation, which I'd fixed successfully years ago on the Goat with POR-15 and fiberglass cloth.

Is the following statement correct?
"Any floor pan from a 1971-76 2 door Buick LeSabre or Centurion, Pontiac Grandville, Catalina, or Bonneville, Olds 88 or 98, and Chevy Impala or Caprice will be the same. (The Cadillac Eldorado was front wheel drive and so won't fit.)"

Any car I missed?

I'm assuming the floor pans for the convertibles and hardtops are identical, and that 4-door car floor pans will not fit.

Thanks.

That's probably right. From 1971 on, big GM cars used the same chassis (and I think) the same floorpans.

i think they are the same 71-76

How about the floor pan being modified in 1975 for the catalytic converter? Did they need to raise the floor to make room?
