I thought I'd pass along some useful tips on identifying rocker boxes. All have the 65-1506 casting number, but:

BB 3/8”-20TPI acorn nut (65-0311). Also, has no threads in the casting for the rocker shaft
CB DB DBD 1/2”-20TPI acorn nut (65-1856). Has ½-20 threads in the casting for the rocker shaft.


Coming to terms with your delusions, is the first step to sanity

Thanks. That is the type of tech info that is useful. I made it a stickie so it stays at the top of the page.


Never underestimate the human ability to elevate stupid to a whole new level!.
