I have a M1028 dually but no data plate other than the original one. It was an Air Force truck, they must not have cared enough about the plate. I have seen pictures of many of these trucks and the rear fender reflectors and lights can look quite different. How how many years did they do these conversions? I have heard that a few came from the factory with the conversion and the opposite, that none did. Mine has the 208, but I have a 205 with the PTO from a 31, Is there an expert or Guru on CUCV's? I would also like to know if all AF trucks were a3's.

I have always heard they were all conversions, but then ran across where a few 1986 made weren't conversions. It would be interesting to know when the conversions started. Like the date on that crate would be interesting. I'm interested to know when the decision was made that a dually was needed and the 1st conversions were made. The dually fenders I've seen have different lights on them. The one I have has tiny lights on it and some others have civilian style lights. I have a 1985 M1028. It has been parked behind a friends barn for 6 to 8 years. It starts easily but dies right away and won't rev up. I have worked my way forward to the injection pump return check valve because it acts like a fuel issue. It is either the pump or pulling air, probably the pump,

As stated above, all military CUCV duallys were conversions.
M1028A2s were also converted from M1028A1s. The only real difference between an A2 and an A3 is the transfer case.

That said, there are dually Chevys out there that were military, but are not CUCVs, they are just similar Chevy 4x4 trucks. The Air Force, in particular, bought a lot of off-the-shelf trucks.

The CUCV lights should have all been the same in military service, but some may have been switched out by individual units for some reason, or been changed by their civilian owners post-military. All M10xx CUCVs were built to 1984 standard and use 1984 parts, regardless of what year they were built.

The military learned their lesson with the M880-series - those were built to whatever standard Dodge was using on civilian trucks during each year of production, so they ended up with several headlight, grill, turn signal, etc. etc. differences between trucks, which caused a great deal of spares and support issues.

Cheers

My truck is an a3. It did start out as a M1028. I'm the 1st civilian owner, but a University AG station had it after it's military service. They spent $zero on the truck so it is exactly like the AF left it. I'm reasonably sure it has the original marker lights on the fenders, but I was curious how long these conversions were done. There must have been a time frame, and the kits that were contracted from GM could have changed things like marker lights, and the rear fenders themselves because the lights have different cut-outs in the fenders where they attach. I was comparing trucks on the net and this difference stood out.

I know that the military bought trucks straight from Chevrolet, I have 2 from the 50's, (one is IH). The were special ordered, have the dash plates. Back in that day you could order a truck any way you wanted it.

I brought the truck home, so I took a couple of pictures of the of the rear fender marker lights to show what I was talking about. I have seen others like these lights and I have seen others on Ebay and You tube that have the civilian style with the indentations in the fender that hold the lights. This tells me that, somebody put civilian fenders on their CUCV or they had kits that were not made exactly alike and probably made for different contracts at different times. That is why I posed the question of when these conversions began, and how long they were done. I hope somebody knows this,and can fill in some of the gaps on CUCV history. This is my 1st CUCV dually. Was there any cover to fill in the gap between the bed and the dually fender. It looks like it would fill up with dirt without one?

Thanks

I don't know. I bought it from GSA. When you say stock GM dually, all of these were conversions from a kit as I understand it. I'm about as certain as I can be this is how the Air Force used it. I don't know what was in those kits. Typically these agency's out here spend nothing on the upkeep, they don't change oil or filters, and when they quit, or blow up, they get another freebie. If they fill it full of gas, or the GP card quits, they spend nothing on it, often they cannibalize to keep one running, but I highly doubt fenders were bought by anyone but the Air Force, since this was an Air Force truck.

That is why I started this post. I have seen at least 2 styles of rear fenders on CUCV's and thought it might have to do with who supplied the Kits and when. Some people may also be repairing their trucks with aftermarket or GM civilian fenders. Took a picture of the inside.

That's interesting. That is definitely not how the fenders on my truck are done, nor any of the others I have seen. My fenders are permanently mounted tight to the bed and have the seam filled, no rubber gasket.

My understanding is that all the kits were provided by GM, and were all the same, including cutouts for the stock lights.

That does not, however, rule out a unit-level conversion using what parts were available at the time. There are no absolutes when it comes to these things.
Since your truck does not have the data plate that came with the kit, I deeply suspect it was not done with a stock GM kit. And especially because it was Air Force. They are well known for buying what they need for a particular use, and have the deep pockets to do so.

When you say permanently mounted, you can't unbolt them?
There is one on You Tube that looks the same as mine, the owner painted it tan. He doesn't mention the data plate and I could not see it, but he does have the same fenders. I'm going to watch it again to possibly see if it is AF.
