Cucv?

Yep. They're more or less a cab-n-chassis -- SRW, though -- with a goofy hole cut in the cab and then that big box on the back.

The only CUCV with 10-bolts is the M1009, the Blazer.

CUCV History And Facts.​
Around 1981, a prototype K5 Blazer was used as a test bed for a military CUCV vehicle. Between 1983 and 1986 (the production years), what is known as the M1009 CUCV was the production militarized version of the civilian K5. The only differences are the lack of an air conditioner and an additional leaf spring in the suspension. A majority of them are painted olive drab green (or in the black-brown-green camouflage pattern used by NATO forces if an M1009 was stationed in Western Europe) until its use in Operation Desert Storm where M1009s were painted desert tan. All M1009s, including its derivatives, are powered with the 6.2 L Diesel power plant.

The M1009s have a split 24/12 volt electrical system. Most of the truck actually runs on 12 volts. It has two separate 12 volt alternators and batteries wired in series, only the glow plug system, the starter, and the jumper cable jack are wired to the 24 volt terminals. Everything else in the truck runs on 12 volts. The glow plugs are actually 12 volt glow plugs, with a resistor pack on the fire wall to drop the 24v down to 12v. This resister pack can be bypassed and the glow plugs run directly off of the 12v battery. If this is done and the 24v starter is replaced with a standard 12v starter the second alternator and battery are no longer needed. (If this is done then the military 24v jump start plug in the grille should need to be disconnected as well)

1.) What was the first and last year for the K5?
The Chevy CUCV's were that I know of, available as 1984 through 1987 model years.
2.) What was the first and last year for the truck?
These are the *Chevy* CUCV trucks. There were also Dodge CUCV's in the late 70's -early 80's, the M880 clan. The Chevy CUCV's were that I know of, available as 1984 through 1987 model years.
3.) Did the K5 ever come with a D60/14 bolt?
No, The M1009's came with 10-bolts front and back, with 3.08:1 gears, six lug; the rears often or always came with a Gov-lock.
4.) Did the trucks ever come with 6 lug axles?
The M1009’s came with six lug
5.) Did the truck ever come with a 10 bolt front?
The M1009's came with 10-bolts front and back, with 3.08:1 gears, six lug; the rears often or always came with a Gov-lock.
6.) Did all 14 bolt FF axles have 4.56 gears and a Detroit Locker?
The others CUCV’s all came with D-60 and 14 bolt FF, 4.56:1 gears. My understanding is that the rears came with a Detroit and the fronts were open, except on the 1028's which (often) came with some sort of traction device (Auburn?)
7.) Do the 14 bolts use the 1 ton spring spacing?
The pickups (i.e., everything but the M1009) have one-ton spring spacing. The vast majorities were SRW; I’ve seen occasional duallies (M1028A3), they were rare and to my knowledge.

In short, if you want axles from a CUCV, you want to get them from a pickup CUCV, and ideally from a M1028.
Other details: The engines are all the J-code intake 6.2L, with a TH400 and 208 transfer case. Electricals are 24V for the starter and glow plugs and 12V for the lights and other miscellany. All trucks except the M1010 had two alternators, one with floating ground, to charge the dual batteries in series.
I the M1010's (Ambulances) had a single 24V alternator because they had air conditioning (none of the others had this).

The use of the 205 had more to do with a PTO requirement in some government contracts. That is what I read in Military Vehicles magazine.

Hows all that look to you all?
 
The text is formated well, easy to read.

The good news is I just pick up an M1010, well won the auction and it's only 60 miles from my house! Now I can start thinking about other things.
 
Dibs on un used parts! A few small peices I want for my collection.
 
Well a guy that works for me wants the ambulance shell. The dash and steering column are gone.

What are you looking for?
 
The data Plates! On door loading info and the id tag on door jamb.
