CUCVs use metric bolts so you will need metric tools to work on them.

The main problems with CUCVs are charging issues and glow plug issues. The original glow plug relay was defective and should have been replaced before the truck left the service. If you have one that looks like the one in last two pictures, you should replace it. Most come out of the service with one like in the third picture. Some of the dealers here have had them in the past. The first picture shows one I got at NAPA. I used ECH GPR109 for $28.49. It looks just like the ECH GPR110 but it is $85.49.

The ST85 looks like what the military went to and is $54.49 at NAPA online or 45.20 at the local store. It also shows one way to bypass the voltage dropping resister. Here is a link to some pictures I took when I replaced my last relay with a ST-85. The old one is what came with the truck from the military.

The 109 and 110 relays will bolt up with the same holes as the original relay. They don't come with nuts on the posts and they aren't the same size as the original so you will need to get some while you are at the store.
