I have a wire wheel on my car in place of a wood spoke one right now. I obtained a set of hubs for the wire wheels from one location and the wheels from another. To change remove spindle nut on front end and remove the whole wood spoke hub/drum/wheel/ bearing assembly as a unit. Then install the whole wire spoke wheel hub/drum/wheel/bearing assembly as a unit. I had to adjust my brakes a bit on that wheel because of the "new" drum. The drums and bearings are the same. Drums could be used from one to the other but new holes would have to be drilled You can take the wire wheel off with the five lug nuts once its on but changing the whole works is just the one spindle nut. Same thing on the rear. Just remove the axle nut. (and get a puller or whacker) Eventually I want to be able to switch between the two easily. I'm pretty sure the 31 hubs are the same. I'll try to get you some pictures.
