I know that this info is prob out there but I'm not sure what's true and what's not. I want to upgrade to a 14 bolt ff with 6 lugs. Did GM make this? And will it fit in my truck? I know that I'll need a new driveshaft. This is what I have, 1972 k10 4x4 swb.

o ya. I would like to have a 6 lug because I just got 4 new mt classic II's with the 6 lug pattern. Can I convert an 8 lug? please help!
