I'll look around again for more farm trucks, but that is what this was, a farm truck. I ID'ed the RH-5s from a picture I found and then confirmed it with the owner. Thanks for the heads up on the 22.5 10's, I'll wait for the 9's. I'll have to look again, but I thought I read a post somewhere that the 8.25's on this truck crossed to a 10 22.5, but I could be wrong. I seem to remember that Chevy 3500HD rims will fit, but the hub hole is bigger and I will need to build an adapter. I understand a late 50's rim is ideal, but they aren't easy to come by.
