    Can anyone tell me from experience exactly what type locker is in the CUCV 1.25 ton military 14 bolt rear axle. I know it is some sort of locking, I've heard it's a Detroit or maybe a gov-loc. I'm looking for someone who has actually bought one and opened it up, not just something someone has heard. I have a chance to buy a few of these sight unseen and am trying to weigh my options before I buy them. I'll also be getting the D60 fronts - maybe. I lnow there's a limited slip in the front. Please help.

    The rears have the Detroit Lockers. Trust me. /forums/images/icons/wink.gif

    The fronts, according to someone else, were a 40/60 deal, where 40% had the Trac-Lok's and 60% were open difs.

    I've only heard ( /forums/images/icons/grin.gif ) of the fronts having the posi in the M1028 or M1031 trucks. M1008's mainly had open difs.

    I'll throw my experience in backing both the pervious posts 100%... And yes, my junk started out as an M1008 so this is not hear-say…
