from what I gather.. the trucks use a g63b engine... the dsm is a 4g63.. while they are close I dont think parts that will fit into a 4g63 (like the 2.4 crank).. wont work in the g63b. plus the g63b was in the early 80s and up..(not sure if it was in the 79 or not)... and the 4g63 didnt start till 89 for the 90 model dsm. I could be wrong so dont quote me on this..
