I have an 87 Comanche with the renix system 4.0 and it blew a head hasket and the rear main seal is leaking. I am wanting to update the whole truck to 97+ interior/exterior and engine. I found a 94 4.0 with 134,000 on it in good shape, the engine in the 97+ parts truck has 180,000 Kinda high mileage for an engine swap. I don't want to spend the time and money rebuilding the 180,000 mile engine.
Will 1997 and newer exterior parts work on older engines like exhaust manifolds, intake manifolds power steering pumps etc. ? I did a search but couldn't find any info on it. Any info would be appreciated.
