I used a $9.95 Mr Gasket chrome universal type for a (gasp) Big Block Chevy. Bought it at my local auto parts store. It has a tab that fits the alternator bolt, and I used a short piece of rubber hose and a couple of hose clamps to attach it to the nipple on the Aviaid pan. Works like a charm. Don't forget to block off the old dipstick hole in the block near the oil filter attachment pad.
