The one in Klamath Falls will be going home with me.

Parts are readily available, as long as you are talking about the mechanical parts. The Red Diamond engines were used through the 1970s, and shared with the civilian trucks. The Blue Diamonds to a lesser extent. The Green Diamonds are harder, but still not that hard. Local engine shop near me rebuilds a couple a year.

The drivetrain components were usually shared with the civvie trucks, which makes obtaining parts easier. The rear brakes cylinders are not usually available, as they were special. Usually you have to sleeve them to get the old ones to work.

The winches were made by Tulsa, Heil, and I believe one other company. Tulsa still makes the same winches, and parts are a phone call away at the local Tulsa dealer.

Bodies were made by Anthony, Heil, Tulsa, and Garwood. The Tulsa oilfield body with the gin poles is actually still made, so you could just order a new one if you wanted. The others are extremely hard to find. In fact, you normally find a body and then just buy a truck to fit it. However, if you don't care about originality, then it really doesn't matter. If you are patient, you can build one by measuring an original and cutting and welding the pieces. That hinges on knowing someone with an original body.

The open cabs are hard to find some parts for, such as the top bows, doors, and windshield brackets. I am working on getting the windshield frames repopped by a company that does that type of thing. If you want a closed cab on an M-5H-6, you can use a K/KB-5 cab or larger. Those can still be found.
