1990 Dodge Cummins 2500 truck... wrecked, bent frame, all running gear there (Dana 60 and Dana 70 rear, 3.54 gears), Cummins Diesel motor with automatic tranny and T-case, 200,000 miles, apart but was all running good before the wreck. Comes with some old '63 Dodge frame with a 1-ton rear end and a closed knuckle Dana 60 front with a 360 and 4spd. It's for sale $2500 for all or make offer... I wonder if I should get it and take on the project of swapping the motor into my '81 Crew Cab. But I really would want a 5spd manual. What automatics were used behind a Cummins in 1990?
