I have a 1943 L-4B which I obtained last year. It has the original (overhauled) engine mounted but is presently set up with a Marvel Schebler carburetor and J-3 airbox vice the appropriate Stromberg carb and L-4 airbox. Thus, I’d like to replace the former set up with the latter, and so far have obtained a Stromberg carb, L-4 airbox and an original air filter. However, I still need the carb spacer and gaskets, air filter bolts and nuts and the air box gasket. Can anyone point me in the right direction to obtain each? Thanks!
