the only difference I can discern is that the 67 manifolds are 3 bolt flanges on both sides vs. 3-2 on the 68-72. Text I've read on it says there's a change in the "runner design" between them but I can't see what's different. I have 67 manifolds on my 69 without a problem so I can't see why going the other way would be an issue.

On F body cars it was steering box location that caused fitment issues. 2nd gen (front steer) will not fit 1st gen (rear steer) cars. Now that's with the round port RA exhaust manifolds.

Thinking yall's cars went to front steer in 68. Not positive, just thinking. If so, the older working on newer makes sense. But may not be able to go the other way.

Just something to think about

okay, I'm only talking from an A body perspective, I don't know crap about F bodies!
