Yes, I have one and I'm real excited about restoring it.
Do you know of any repros made of steel? So far, the only ones I've seen were fiberglass. For me, anyway, the steel ones would be easier to modify for the wider width.
Otherwise, I've been thinking that if I have to make some, my best bet might be to find another set of 1-1/2 or 2 ton "front" fenders (with the larger wheel opening), cut them parallel to the outside face, and then weld a strip of steel along the inside edge, wide enough for the duals. It's hard to explain in print, but I think it might work. I'm thinking front fenders just because they seem to be more available (and less money) than any size rears. Any thoughts or other ideas?
Thanks again for all the help,
Bob
