I need your advice, knowledge and input. Last year I picked up a B6100D 4WD that was cheap; but very rough and needs a lot of parts and work. I just hauled home a B6100E 2WD that is in good mechanical shape; but is inoperable because it has a bent steering shaft resulting from a rollover. I want to use the parts from the 2WD to fix up the 4WD or use the parts from the 4WD to convert the 2WD to 4WD. Could anyone tell me what I would have to do to convert the 2WD to 4WD?
