Part and casting numbers are two different things ain't they? Saved from who knows where an old blurry image file. Is this propaganda of unknown origin that now I've typed up anywhere near accurate? Or is it already posted here somewhere?
( EDIT ) well crap, below are all PART NUMBERS I think, NOT CASTING Numbers, which was the goal, so I think this list is bullshit maybe. And looking at the 67-72 Parts Manual this list is NOT complete either.

Well crap, the list I typed up from an old image file is Part Numbers, and Casting Numbers is what I was after. Like those visible on the manifold pictures Rick posted, Thanks.

It is a bit confusing... In 1971 the big cars had Free Flows for both sides. The 4 speed cars had air tubes and the automatics didn't. The small cars had a Free Flow on the left and a log style on the right. So in theory there should be 4 part numbers for the right hand exhaust manifold for 1971. 2 with air tubes and 2 without.

Looking at the 1967 to 1972 AMC Parts Manual and that list is not complete...
