Any one find or have their/others build sheets?

Thanks John.

How about anyone with the "Keep your GM" tag still on the air cleaner?

Here's two from my previously owned '70s, TX & CA cars.

Original decal placement...

I bet that blue one was a good looker?

The 'RC' for California emissions, Mike?

:)

It was a great color combo...

That is nice.

That interior shot really pops!

I love these GP's!!

Thanks.

RC would have had the vent hole in the base for the XT (7040568) carb. And would have been the non-HD unit.

Did they make 400/4bbl GP's in '70? Just trying to see if there was a difference in air cleaners.

They sure did!

The Grand Prix used the same 'base' drivetrain as the GTO & Firebird Formula - with the exception of (as I have understood it) the GP's pretty much all used #13 heads.

I would think that the GP used the same aircleaners as the Tempest/Lemans/GTO.

While the 4 bbl. bases may be the same (excluding F-body), they may have had one or 2 snorkels (what I'm trying to figure out). And California emissions would have had a vent tube hole in the 4 bbl. base. GTO's had a chrome lid which gave it different PN's. There were something like 16 different air cleaner assy. PN's for '70 Pontiacs alone (excluding the Firebird/Trans Am).
