Need help trying to figure out exactly which casting part numbers applied to the 1968 Firebird RAII long branch manifolds. Lots of confusing info out there on various forums.

The options seem to be:
9794038/9794036 or
9794038/9794037 or
9794038/9797074

I have a rather old RARE catalog/handout that I picked up at the Ames Norwalk event 15 years ago which says their castings show the '69 Firebird RAIV p/n's 9794038/9797074, but that doesn't help me with '68.

Need help understanding what was correct for the '68MY RAII birds.

Thanks!
