I am getting ready to do the nv 5600 swap into my 98 ram. This means I will have the nv 4500 out of it laying around. Its in decent shape. My 92 model d3500 has a VERY tierd auto in it. Can the 5 spd from the 4x4 98 be put in the 92 model 2wd that currentely has the auto? what kind of problem will the rearend gearing of the 92 play. I guess it will be more trouble that its worth but I sure do wish it will work.
