Well, there are various sizes and bolt patterns on that chassis. For me personally I don't know what pattern I will look for. I plan to take the axle and front spindles and disc brakes to put on mine. Might look at what modern wheels are available and match up the bolt pattern. I do know that the 10 lug on 7.25 with a 5.25 bore is available on them. I have a set of 19.5s on my bus now that came from an RV. many of the guiys here don't like the look of a smaller wheel, it suits me fine for my project plans. It will somewhat depend on what you are doing and what you want your bus to look like.
