Pep Boys have a ready made adaptor plate that allows you to slap a 4 bolt base 2bbl on the "4bbl only" Offy C manifold. Its supposed to let you put a 4bbl on a 2bbl manifold, I just flipped it over. A Autolite 2bbl base gasket is a perfect fit. $20, lot cheaper than having the local machine shop cut one out of 1/2 Al..... the game is afoot!
