Well after thinking things over, I was thinking the best thing for me to do is see if i can put my first gen body on a 2nd gen frame.
I got a D350 that Im turning into a pulling truck. I was going to swap everything from a 2nd gen 3500 to the 1st gen frame. But after thinking a bit, it might just be easier to put the 1st gen body ontop pf the 2nd gen frame. Reason being is it would be a TOn of work to get everything mounted i.e. tengine, transmission and transfer case. If I get a rolled or wrecked 3500, scrap the body and then use the bare frame that already has everytghing mounted up.
Im not really worried about drivetrain hitting the floor...its just a pulling truck, a hammer or a cutting tourch can fix that!!!
But how far off are all the mounting points for the body? Bed should be easy, its only 4 bolts! What about frame lenth? am i going to have extra lenth to worry about???
