Pulled the overdrive crossmember out of a 1992 B250 conversion van. Cut out the original one in the 1979 and welded in the 1992 piece. The new unit has a beefy steel inner bracket 19" wide hidden beneath the stamped outer sheet metal. It also is shorter allowing the overdrive transmission needed space.
Also modified the transmission bracket to shift the transmission and engine towards the passenger side 1-1/2". The coil packs on the driver's side need the room.
Pulled the motor and welded up the relocated factory passenger side engine mount pedestal. Finish welded the engine mount brackets I made. Added gussets to the brackets because that's how the $300 aftermarket pieces for a Dodge pickup look. Plus I like welding.
And a coat of semi gloss black. For that cool look.
Driveshaft is out. Needs to be 14" shorter! This 1979 had the A727 with the bolt in output yoke. Very short compared to the A518 with overdrive. I'd say 14" longer.
