Diesel Bombers - Trying to keep my 92 roadworthy!

I have had a 92 since 1993 and used it as a shop truck for Sass Patterns. It got very tired and I finally had to put it out to pasture, at 450,000 plus. Two years ago I found a 92 D350, with no drive train, but in really good shape body wise. It had belonged to a trucker that blew the engine at nearly 300,000. He had started to rebuild the engine, and while that was being done, he stored it in a terminal warehouse.That is why the body is in such good shape 9 years later, when I found it. I don't know why he did not ever finish his fix, but I found an engine from a 93 with only 107,000 miles on it and now I am trying to bring the truck back to life.
