It appears that your axle fits 37-39 Fords. As far as the V8 60 is concerned it was first available in 1937. It was a 136 inch Flatty making 60 hp. It was actually a down sized version from Fords 85 hp engine done in the name of economy and gas milage. The real handy thing was that it fell between 100 and 140 ci and thus met acceptable numbers to the standards of the Midget Racing world. When they were hopped up they were the nemesis off the Offy. Pretty neat little engine!
