Hey Kevin! That will make a nice ride around truck. I have an 88 D100 long bed with a 318 that I'm gonna swap a 98 5.9 Magnum into, hopefully this coming winter. My 88 is the 5.5 bolt pattern. I'm gonna keep it 5.5 because it has factory rallye wheels. I have a early 70's D100 8 3/4 to swap into...
