Same 20" ten-lug wheels as the Dubl-Duti...
The big giveaway on axle ID is the cover for the front wheel bearing...the medium-duty axle has that screw-on cover with the octagonal head; the Dubl-Duti axle has a "domed" cap secured with five 7/16" head bolts.
When you look at the king-pins, the medium duty have welch-plugs covering them, the Double-Duti have the oval flat cover with two bolts.
One of these days I think I will try to get a resto packet from GM on this buggy...
It looks just like a '54, except the grille is painted all-white ('54 was body-color on the outer bars, with light gray on the backsplashes).
Good luck with your wheel adaptage...sounds ambitious !
