I Have a 1941 GMC one ton dually, got around 2003, just started driving it .Its got a GMC 270 with the old 4 speed, top speed about 45, fun to drive.I built a wide bed and added rear fenders, trying to get that new dually look, turned out good.My only problem is it has the old GMC 6 lug 7 1/4 bolt circle front hubs. I have collected some parts to change to 8 lug, got hubs, got the 11 inch drums here on stovebolt free, now the hubs dont fit my spindles,I may have a machine shop make spacers for the bearings,or ,IF I could find another axle here in Florida, that would work.
Anyway its fun, ill try to get some pictures posted.
