Ok, I have run into an issue that I have “fixed” just not happy with it and your base looks beautiful. Not to hijack, but I run the stock 68 340 unsilenced air cleaner. Which only allows for maybe 1/4”-3/8” gap between the lid and the base for all the air flow. Which is insufficient for my combo. So your base fits the eddy thunder/performer carbs and is how big in diameter? I would love to find a base that would give me a much bigger gap to my lid.
