Drtheo,
I do have a pair of 1-ton dually's, 1947 AD
Jerry about sums up the complexity of tires, rims and brakes. The rear brake shoes are not available. One must have them re-lined. The drums are scarce. The spring between the shoes on the bottom is available from Carters. The retention hardware clips are scarce but you could use snap rings instead but you will have to hunt around. Master Cylinders are larger bore but available. Rear differential swaps out to a more drivable 4:10 vs. the 5:14 stock. Not much else to say. Most hardware is available, kingpins are out there too. The rest of the truck is similar to a 3100 or 3800. They are easier to work on, one could slide right under and change the oil and snoop around.
Leaf springs are not available through the typical vendors and you need to check the front lower leafs to make sure the bolt hole is not egged out. She will wander if it is. There are companies out there to bend new lower leafs if you find it worn.
I say buy it.
Joe
