'49GMC,
Do yo have access to a welder??????
A last resort trick that I have used many times is to weld a length of flat bar stock to the wheel nut/stud ( whatever is easiest to get to ) and then you can lever off the end of this with a big shifting spanner, or in extreme cases, weld a handle to the end of this piece and use a length of pipe to get more leverage.
One of two things will happen......if you manage to get the weld onto the wheel nut, the welding heat and extra leverage should budge it.......or the stud should snap clean off.
If this happens, it is easier to centre punch and drill out the studs.
P.S. A few hefty blows with a FBH and a piece of timber to protect the rim may even shift it!
