Exhaust ports are the same. A Cherokee header from 91 to? will work but you have to file the intake manifold a bit, add an EGR tube bung, get a new downpipe with an O2 sensor bung.
Done it a coupla times.

Ok quick question, my jeep is a daily driver, plays in mud puddles, fire service roads, camping trips and some light wheelin. It's a 5spd with a 3" lift and 31's.
Question is would it be that beneficial to me to swap in auto axle's and swap to a non disco d30 front and a 27 spline c8.25. I know the 29 spline is stronger but for my purposes I'm sure the 27 will do just fine. Some day it will get lunch box lockers as well. So should I get the axles and swap them in or just get a c8.25 and save for 3.73's?
