09 Charger rt wheels on a 66 plymouth fury

no don't mill the wheels just buy acorn lugs that fit your fury studs. Are you trying to use "shank" style nuts off the Fury? Use the conical seat, and if you need more meat on the seat use "bulge" conical seat. look up Gorilla 61187 on summitracing $16 for 4. Or for less the Summit brand 754006 for $1 each. Do you have all right handed threads?
