1998 3.0L transplant... 4WD-5sp to 2WD-auto

[djjauntyj]

Hey folks... so as I wrote in my intro post, I have a '98 3.0L/2WD/auto truck that I'm pretty sure needs an engine. I have a line on one at a yard about an hour away, already pulled. It's same year, 148k miles, but out of a 4x4/5-speed truck. My plan would be to go through it with the typical gaskets/seals/timing set/cam synchro/etc. But, what else should I expect to have to do in terms of adapting the "new" engines? What should be the same and what should be different between these two engines? I appreciate any answers I can get!
