Have a cast aluminum adapter that allows you to fit a dropped base air cleaner pan to any carb with the 4 7/32 air horn diameter-specifically 4GC and AFB carbs---they only raise the air pan up about 5/8 inch from the carb so if clearance is a problem this might fit-- I also have several air pans left that will fit this adapter ---$50 shipped anywhere in the US---when they are gone they are gone --might not do this again-- you need pictures email me at
