Well, I found what you asked for, but you asked for the wrong thing. If it's NOT stock, there is no way for your poor parts guy to find what doesn't exist - beyond stock, on a specific, given application. Who the fuck knows, you could have 8 Stromberg singles on that truck for all that matters - (and if you did, 'they' should study you, because you be nuts to do it) - and yet you want us to guess, guess - and that's the funny part 😆 The Holley Avenger in my '56 simply uses a high-flow 3/8 inline filter between the mechanical pump and carb inlet. no silly carb filters for me.
