Replacing studs on K-H setup?

I never shop at China Freight. If I need a tool, I'm willing to buy ones that last.

If the old studs are really bad, a heavy brass drift and a big hammer should drive them right out. Yes, the rotor must be on a good solid surface. The hub & rotor are held together by the studs on the K-H brakes, but with two others unmoved you should be good. Make sure the replacements match the old ones removed.
I didnt want to shop there, but was in a pinch. Do you know anywhere that would sell a single die (a good one)? A GOOD die may have worked..the cheap one just would not start straight, like it wasnt sharp enough. Plus, i need a hex shaped die so i can turn it with a wrench because the die holder hits the center snub..
