While likely not a faithful reproduction of the original oil filler cap,for all intents and purposes have a look at the Mr.Gasket chrome cap for the big block(and likely the small block too).The package states it fits GM 70-80 or something to like effect.Picked one up at a local NAPA store for $5.00 Canadian.It looks much better with Stage 1 covers(the chrome is very good) than the anodized aluminum one that I had .If you are one of the more erudite,effete autophiles then pretend you didn't see this.I forgot to get the part number before I tossed the packaging.Another satisfying piece at little cost-a rarity.
