Hello,
I am new to the forum and it has been 25+ years since I last tore into a Mustang, so please bare with me. My Mach 1 requires a Autolite 4v carb with part # D0OF-AD. I have one. I also have another of same thing but part # D0OF-AB. I know the AD is for 351C4v, CM and AC. I plan on rebuilding it to factory specs and I bought the other as I thought I could use two to make one nice/complete one. However when it arrived it was the -AB number on it. Too much trouble to return so I thought I would ask if they are basically the same and if anyone knows the specific differences. I already know it is for a 4 speed 351C 4v. Is there just basically external parts or is there internal differences.
Thanks,
Dan
