67/8 air cleaner base plate

Rani 67 base is for AFB (small), 68 is AVS/Holley (big).

All you need is the full size 68 bottom and cut the lip back to make it work for the unsilenced top. It looks like that was all the factory did anyhow once you see a factory one.
I don't know why but the bases are always missing. The bases are more rare then the lids which are on the top shelf with the hens teeth and duck lips.
