Checked Golden State and Brothers and they both sell the 6-lug kit. My 59 suburban has a later-model 12-bolt 6-lug rear in it now. It is a posi with nice highway gears. I also have a 71 camaro 3:42 posi complete rear end that I could put in the truck then put the 5-lug setup in. That way I would have 5-lugs all around... decisions...decisions... Probably just go with the 6-lug setup. No problems with the rear in it now so if it ain't broke... well.. you know the rest..
