here is a tip for those "lug bolts". get another hub/drum for the right side [the driver's side is left hand thread as i recall], then use 2" long "button head" capscrews that are threaded the whole length with a little thread locker[blue] - viola,instant "modern" studs. or use moroso,summit, etc. wheel studs. they may need a slight trimming on the heads and the length may need trimmed also [if you don't need the whole 3" length].
