Thinking of swapping a 90 4.0 from a auto into a 89 2.9 with a manual I know the wiring harness from the firewall out is needed with radiator & ill need a ecu from a 4.0 manual is there anything from the 2.9 that can be used? Flywheel,clutch etc? THANX!!
 
honestly, i think i'd use all 4.0 stuff. unless you have the 2.9 md05 which is lower geared. mine is an auto so idk the strict details about the swap on the manual
