Mine are hub pilot motor wheels, as in not Budd style. Also mine is all right handed threads, and unless you need to keep it pure for the parade resto, you can put RH thread studs on the left side of the rig, since that's what they started doing to the same hub and wheel combo from the factory, anyway.

His truck has wheels like mine, according to the picture.
