1968 Carter AVS Application Question

Carburetor Update:

I feel silly, but I didn't realize until now that the carburetors had date codes on them. Because my 4636 carb has an E8 (May 1968 ) date code, it could not have come on my car which was built in January 1968. Always learning!

The great thing is that I just found a 4425S with an October 1967 date code.
