Were there more than one length of hubs used on these cars. Meaning Depending on the use of the car. For instance Are wire wheel hubs shorter than pin drive hubs? I know some converted spline drive hubs to pin drive. Are hubs on competition cars different?

My front hubs use the longer axle. So the bearing races are spread apart a little farther apart and outside bearing dia is larger where it mounts to the axle. It uses a lm 12749 instead of lm11949. I think this hub is still about the same length a hub used for the shorter axle. But internally the races are spread apart further.

So were there different length rear hubs?
