67 383 Unsilenced Air Cleaner Base

Thanks for the info. I will keep trying for the original for a bit. Isn't that Mr gasket adapter too small at 4 7/32? AFB's are right around 4.5". Unless you have tried this set up with the original top and saw that it works?? Thanks.
4 7/32 ID is the right size for early AFB's. I might have an original base, will check tomorrow. Or you can find a standard base and cut the outer diameter to the filter pad. That 4 7/32 ID is used on most AFB's up to 1967 and larger 2 barrel carbs on big blocks.
