After Market Carb

If there is a thin metal tag held on by one of the screws, that is the Carter P/N. They probably had a Bill of Materials in their files listing all the parts needed to build that particular model. Anyway...you can Google that number and find the exact application. I'm pretty sure they were listed in the FSM too. (Factory Service Manual) A 77 Volare carb should be good for you , especially if it came off a slant.

I bought a BBD off EBay last year and the tag told me it was originally used on a 1967 273 manual transmission car which should work pretty well on my stick shift 64 225.
