Its unlucky that your wheels are in need of replacement when the rest of the truck is so mint. Have you pulled them all apart? Mine has the same wheels, in the three piece rim. These will handle a fair bit of rust before you'd have to abandon them.
I had to search far and wide for useable ones. You will too. I found that bead blasting and then heavy zinc paint worked well, followed by two coats of enamel.
You will have the same rims front and rear- the fronts have a cover hiding the unused holes. They look like the three piece rims- The main wheel, the separate outer rim and the lock ring. Best to pull them apart and see what they look like. Are they damaged? They look ok. But yes- nothing saves them from centrifuging in water in the wet, and then standing for 60 years will rot them out.
There is plenty of wheel info on the forums here, and no real easy answer. Best of luck.
