So I have been looking for a decent square body for some time now. Didn't really have my eyes on anything in particular, but the frame and body needed to be in as good of shape as I could find.

Last week I came across this beast on marketplace up in Massachusetts. It's a 1986 Chevy M1031. Which is the military CUCV service truck.

It is I'm great shape. Frame is rock solid, and the cab has very, very little rust. It is also mechanically sound. A couple little leaks, but that's to be expected.

It has the 6.2 diesel, th400 trans, np205 t case, king pin Dana 60 front axle with a limited slip, 14 BFF rear with locker, and 4.56 gears. The service body is all aluminum. It used to have a PTO driven generator and air compressor, but those have since been removed. The PTO is still on the t case though.

My plans are to keep it fairly original, but add a few creature comforts to suit me better.

Haha I'd also need to get the rear shaft shortened and the front shaft lengthened.

And source a trans lol.

Got another puzzle piece today. Got my fuel filter head for my spin on conversion. I'm planning on using a cat 175-2949 filter. It's a 10 micron filter and water separator. I'm however debating getting another filter head and running a dedicated particulate filter as well. I'd prefer something that filters smaller than 10 micron

Now that the weather is starting to cool off a bit, or at least later in the day, I'm gaining motivation again to start to work on stuff.

I still need to finish rebuilding the turbo, but besides that, I just need a downpipe flange or dow pipe I can modify then I'll have basically everything I need for the swap.

Today I also started to strip the clear coat off a set of PYO wheels that I'll be painting the same black as my bumpers and all.

It began to rain so I packed it in for the day. But most of the clear coat is off of them. Just need to apply more paint stripper and then get the rest off. After that I'll sand down some of the spots that are corroded and prime them with self etching priming and then wrap it up with paint.

I'm going to try and get the fuel filter done today after work. I really wanted to start the turbo swap, but I still haven't gotten the turbo done yet and honestly I'm debating just buying a new one at this point since there's still a lot of carbon I cant fully clean off of fairly critical surfaces.

Got my fuel filter conversion done. I just removed the line at the factory fitting on the frame and ran rubber line up from there to the filter head. Then the factory line from the filter to pump fit right on perfectly.

Electric pump made priming the system super easy. Cycled the key 3 times, let pump run until it shut off, and fired it up. No leaks so far which is good.

That'll be gone when I do the turbo swap. It'll be a aluminum intake top.

Putting her to work right away (bonfire night). Definitely has a slight touch better pickup with the new filter. I had a feeling the old filter needed changed.

Update after driving the truck more. It definitely got a touch of power back. Pulled the hill going to work yesterday and was able to maintain speed for the most part.

I'm tempted to turn the pump up a little, bit I think I'll wait until I do the turbo just so I only need to do it once.

Burning all of those nice looking pallets!

Crazy what a new filter can do

Haha yeah we stack them up at work and don't do anything with them. So I take them and burn them for fires lol. A lot of them are damaged or the cheesy plywood type that break if you look at them wrong.

But yeah, I went with the cat 175-2949 filter. It's a 10 micron filter with water separator. The oem filter was also a 10 micron filter.

That thing is sweet! If I had the room I'd definitely be buying more square bodies lol. There's just something about them that never gets old. Easy to work on, and basically endless possibilities with them.

I paint matched the light bar I've had since basically I bought the truck tonight and installed it. I matched the color of the bumper. I'll see how it does and if I need to aim it different once it gets dark.

Still running the homemade fuel? How's it been doing?

Not lately I haven't. But I also haven't been driving the truck much over summer. It's been my daily the past 2 weeks so I may begin adding some oil again.

Is that the truck number next to the left marker light, or numbers you live by?

Lol. They were like that when I bought it so I just left it as a joke haha.

But technically to be military correct, it should be a 04 to 06 for 4 tons-6 tons. Each number is equal to one ton. So for just the truck, no trailer, it would be a 04. With the truck and a trailer, it would be 06 for 6 tons. But for a trailer it would also need the "C" designator above the numbers to indicate its a combination.

It is the "bridge plate". This simply let's the engineers on something such as a floating bridge or the like, know how much the vehicle weighs in order to make sure the vehicle can cross without issue.
