So I have been working on restoring little parts along the way of my build. I have also collected the airfilter housing (stock) and the buckets for the carbs. I noticed after I sand blasted the parts and got them ready for plating and powdercoating that they are different slightly. The clips are of different sizes (length) and I can only assume that this is a difference between carb and MFI bases? any idea? Which is for what?
