The FOX .45 has had many changes since its introduction. Too many to try to make finding parts easy. Also as parts changed slightly, numbers didn't. Parts interchange but appearance may be different.

Shown above is the first version. Full as cast fins on crankcase, bump boost port, as cast head and was available in both Ball Bearing and Bushing Versions. I think this was the best looking of the group

The muffler mounting hole spacing on the early version is 0.937" (15/16") and 1.100" on later ones. We do not have mufflers for the early versions at this time. Easy to see as the shape is different.
