The Dakota shifter is positioned further rearward.

As for the torque rating, yes, Dakota is 40 lb/ft higher rating, but I have never seen a reason why. You would think by now someone would know and give reason but I have yet to see it.

Dakota transmissions are easier to find, usually had V6's in front of them which should equal less wear and tear than the V8's.

Sounds like a neat project.
