2 ton truck rims

[Bluehills 42 2ton]

Hello everyone I’m new to the forum and I’m currently doing a frame of restoration on a 1942 2 ton truck. I’m wondering if anyone knows if there are any rims available to purchase I currently have the split ring rims on the truck two of which were flat and after cutting one tire off and finding the rim very badly rusted I was hoping to find a couple of replacements any help is greatly appreciated thanks
