Help cucv 6 lug rear axle

[sante]

guys
I have a 1985 cucv pick up 6 lug, the rear axle went bad, according to my mechanic the entire internal are wiped out. I called numerous junk yards , I even bought a complete rear axle off a chevy 1/2 ton truck, the internals are different from mine and will not bolt up to my truck.
the mechanic stated my old axle gearing is 308, the cover has 12 bolts, we can't find an axle anywhere and he states my axle is custom made, (find that hard to believe?) we called napa they said they can't get the parts (carrier). I spoke to a military mechanic, used my 34p and can't find a parts number for a complete set of internals? Is my truck this rare? I have never seen a six lug truck my other truck is 1986 8 lug, which needs a rear section of frame from cab back. Any and all help would be appreciated. U can even call me on my cell 518-376-2343, BTW I hope I posted this correctly.

If you have a CUCV truck with a 1/2 ton rear you have been duped. The trucks has 14 bolt FF rears. The Blazers M1009's have 10 bolt cooperate rears. 3:08 is the correct gears. If you want to drive down to exit 90 in Pennsylvania I will sell you a good rear axle complete from an M1009.

And when you say internals. Do you only need the locker part? Center carrier? Are your gears reusable?

According to my mechanic, I need all the internal parts, carrier, gears etc.

what do u mean duped? I was told by military mechanic that my truck is early and they were 6 lug . The front is also 6 lug, will a m1009 rear end fit?

Somebody swapped your truck out to 1009 axles. Go see CUCVRUS and get the 1009 axle. Just swap it out. Less work and prob better in the long run.

I wish it was that easy, but it aint . My truck has 12 bolt rear end, 10 bolt front end. My mechanic measured his m1009 and it will not fit my truck, He states my truck has 1008 heavy springs and shocks and the shocks and springs r mounted reverse of a civilian axle and the mounting points don't line up. I gonna go take pics of it tomorrow.
Thanks Sante

Sounds like it was an M1028 , does it have or did it have(look for the spring stops on the sides of the frame rails) rear helper springs?

If so, probably someone removed the front and rear axles for the rear locking diff and the front limited slip diff.

Can you post a pic of your transfer case lever also?

Sounds like that g80 (govbomb) grenaded & tore everything else up with it.
Bet an early 70's 12 bolt axle was swapped in.
The spring pads have different widths and the 1/2 ton axle will have the pads welded farther apart than the original.
Like you mentioned shock mounts are opposite also.
Ujoint size is different, could have a crossover joint in it.

Where did you get the truck from? Straight from the government or from a private individual?
