I've finally been working on my M715 again. I'm putting a 3.9L Isuzu diesel into my truck with an NV4500 5 speed. The transfer case had to be relocated so I moved it back a few inches so that its centered between the axles. I cleaned and resealed the stock transfer case and reinstalled. I'm hoping that with the lower rpm's of a diesel I can avoid heat issues. Also replaced both cab corners and welded in 2 new rocker panels. God the cab sprayed in primer with bed liner on both sides of the floor. Here are some pics of my work so far.
