As it turned out, the studs are the same front and back. All are 1/2-20 studs and all the lug nuts are 60 degree so, it's all uniform regarding hardware. I do intend to replace the front studs with some high strength studs. Finding what will work is another chore. Surprising what needs to be known to do that.
The thread did change as it progressed because of things I didn't know and things I couldn't remember. The thread has been very helpful in sorting out everything. I think the problems are solved and the project is moving in the right direction of having uniform wheels, lug centric bolt patterns and uniform tire sizes including the spare. All it takes now is money.
