There is a build thread here on Moparts, in the street rod section: "49 Dodge pickup on a 96 Dakota 4x4 chassis." See pic below.

i used the entire drive train and wiring harness from a 44,000 mile 96 Dakota 4x4. Everything is intact from that Dakota pickup I pulled everything out of (the bottom half of the frame was rotted away).
My buddy has a full range scanner, but it will be mid week (this week) before he can get to it to make the scan. I'd rather have an idea what to expect, if possible, before I just drop the pan and have a look. Ordering parts online myself to have on hand costs about 1/2 of what things cost to have someone else order them online here locally The truck is still transportation for another couple of weeks. Gene
