Big Block Dakota

Did you have to move the radiator forward? Also, have you considered a explorer 8.8 rear? I have a 87 dakota and I put one in my truck. Its about 2.5 in narrow then the 8.25. They are 31 spline, factory posi units with carbon clutches are $230.00 or less. And you can find them with 3.54-3.73-4.10 gears along with disc brakes.
I really do like your truck!!
