Hey guys I have a 1989 d100 that I'm buying tomorrow. It's a 6 cyl, auto longbed. What I'm wondering is what are the dirt wrenches between the d100 and d250's when it comes to the frame? It's 2 wd and is staying 2 wd. Obviously I would need the engine, transmission rear end and probably the gauges and wiring as we'll (parts truck haha) but is the frame the same dimensions? Would it be just some suspension swapping around or what?
