1946 Ford 1-ton 17" rim problem

[ebruns1]

Hey Fellas,

Thought I would share my new project and ask for advice at the same time! I just bought this '46 tonner with a re-built engine that I thought would be simple to get up and running. It needs new tires and one rim looks "iffy" so I thought i'd replace them all. Boy was I surprised to find that the 5x6 7/8 bolt 17" rims were going to be impossible to replace with a modern rim! Here's some photos so you see what I'm talking about. Is that a "split rim widow-maker"? I was following another thread on here about a similar problem, but those rims look different than mine. Is there a modern substitute out there? I know I can have custom rims cut, but at $400+ ea. that's out of the question. And I'd rather have a more commonly available rim and tire size so I can get them serviced if necessary. What do you guys think I should do? Any and all suggestions welcome.
PS - want a driver, not a concours show truck if that matters.
PPS - if I swapped out the rear, is it possible to swap the front hubs to match?
