the other case half
the cam side of the cases has a stop cast in it. Gene Harper shared, with the stop machined out a later model pinon race could be used. and the cases could be line honed. this is very helpful seeings im using miss matched cases. i ll share more of the line honing later with the help of Jim Wall. here is a photo of another good friend Rudy. while we bored the stop from the cases.
Thank You Rudy !!. you should have smiled..
