Randy, been waiting to see your progress.
As for how to solve your wheel issue, there are several ways to go on this. Maybe the easiest and possibly the cheapest all around would be to find a custom bike shop and have them fit a bare hub to your axle, then lace up the correct rim (probably the one you already have on hand!) to match your bike's.
Next best option would be to find an axle stub to fit the wheel you have, then find a good shop to weld it onto your leading link. Alignment is quite critical here or you might experience tire wear issues.
Again, I wish you were closer so we could do the axle stub swap together.
