I'm likely going to go with a similar setup without an intercooler as well. I'd be happy to get together sometime when mines completed.
I dream of the day pulling into the York Jeep show with this truck and a load of MJs on a trailer. Hahaha
Going to try with the Dodge radiator. Probably will not mess with an intercooler at this time, since this era of Cummins was non intercooled to begin with.
Welcome. For your 4wd swap needs the consensus is to find a wrecked XJ Cherokee and utilize as many components from it as you can. Everything from the B pillars forward are identical. Not sure though if you can keep your 2wd transmission...
