6 lug wheel ?'s

[npc1]

Ok here is my question/questions. I recently bought a 67 chevy shortbed stepside. I have looked all over the web and I have seen where people do the 5 lug conversion so they can have disc brakes and have even saw where they sell a complete conversion kit. In those kits they offer either 5 lug rotors or 6 lug rotors. Now my questions are I know the 6 lugs are 6 on 5.5 but they have a 7/16 bolt thread size. I am wondering if anyone has seen or done the newer (2005 & up) 20 inch chevy wheels by changing out the lugs on the rotors and axles to fit those wheels. Not sure if this makes any sense or not but I like the newer chevy wheels in the 6 lug and just need a little advice from anyone.
