1940's HD side car wheel/hub question?

I am looking for a pair (2) of harley davidson wheels or just the hubs from a 1940's HD side cars. they are to be used in a restoration od a vintage 1950's front engine dragster. the original builder of the dragster bought and used quantities of WWII Harley side car spoke wheels. he had the inner race's removed and replaced to fit them (wheels/hubs) to 1948 ford spindles. I am able to get the spokes and the 3.0" X 19"rims from modern sources but cannot fine the hubs. the next best thing would be hub dimesions or drawings to machine new hubs????
please reply back with any and al help or email me.
thank you
