7042264 and 3264 Bowl the Same?

[Ponchojoe]

Hey there, I have a buddy that cracked the fuel inlet on the bowl of his 7042264. I have a 3264 in my stash, is it the same and can be used with his air horn and throttle plate?
Thanks!
Joe

The main castings will physically interchange however the 1973 is a "hot-air" model and the 1972 is "divorced choke".  So there are differences in the castings, vacuum supply to the choke housing, mounting pad and tapped holes for the choke pull-off bracket, etc.

I would recommend locating a 1971-72 Pontiac main castings instead as they are a direct swap......Cliff
