how do I adapt 5x4 with 1/2"X20 stud to SS cragars

I upgraded the 7/16 studs to 1/2 inch on my SBP axles. I had to drill the drums out, but the steel Rallye wheels worked as is. Ehrinburg says the 1/2 inch studs are twice as strong as the 7/16. If you can rework the aluminum wheels, that's the way to go.
