just lean it up against the side of the house! 

I'd really like to get a 8.8 in the rear. Could get lokka lockers front and rear for 400. But I want to go to 4.56 so I would need to get a new carrier for the front.
x2 to all that..Got a reasonably priced junkyard around? Any ZJ with a V8 should have 3.73s... swipe the carrier out of the front diff. They are low pinion but the carrier is the same.
ECGS has 3.73-up carriers for $64, but you can probably get one for under $40 at a junkyard, especially if you rip the spiders out. Good opportunity to grab a spare set of big-ujoint axleshafts at the same time.
Maybe?
I know they have XJ and ZJ marked on the computer module for the OHC, so I'm not sure if there is a firmware difference or something.
97+ XJ OHCs have a few weird year splits (mostly on wiring harness plugs and such) and get data via the CCD bus, I don't know how the ZJ ones work.
They sorta do.
They have their own unique connectors for a few things, like the transmission solenoid/sensor connector and a few others I can't think of. Probably the OHC, too.
They have an RF remote keyless entry like 98+, but it's mounted in essentially a blanked-off IR remote keyless entry "dome" that gets mounted in the 96- spot.
The TCU is unique to that year, so are some other things.
I wouldn't be at all surprised if the OHC module and harness connectors where they plug into the instrument panel harness are unique to 97 as well. My guess is that the split I'm talking about is either 99 down vs 00 up, or 97 vs 98 up. Not sure which and I could be completely wrong.
