2dr and 4dr XJs share the same flat floor, so their floor brackets are very different than MJs. you'll need to mount the XJ sliders on the MJ floor brackets. pretty easy to do.
but 2-dr XJ buckets do lean forward like MJ buckets (4dr do not), which makes them more desirable for us. :)
yeah, I regret not being able to keep mine when I sold my 86. :( plus I guess I don't really need a collection of axles. lol.
my new favorite rear axle suggestion is the Liberty 8.25 as my '06 is a couple inches wider than an MJ stock axle (to better match the wide MJ bed) and can be had with factory disks. plus KJs are super plentiful in the junkyards.
If I was starting over, I'd swap in a non-MJ prop valve up front (XJ, WJ, etc) and then an adjustable one for the rear line. Seems that gives you the best chance at dialing it in juuuust right. :)
in theory, each account will have plenty of space and the pics will be automatically resized. :) in theory. it's all in the hands of Alexia right now, and his real life trumps the digital life so we need to be patient. :) good things are comings...
mine went bad in '99 :D but I found out at work and apparently the experience of trying to bypass the connector in a blazing hot parking lot stayed with me all these years.
I figured out how to merge topics! yay! although Don, the second post looks to be a JK pickup (aev?) so you might want to adjust your text. good comparison though, new to old.
I'd still drive one. :D but there are a LOT of rides in front of that one in line for my (theoretical) money.
welcome to the addiction! :) the forums are a bit of a mess right now (in the middle of updating the software), but there's some good reading pinned at the top of the DIY forum.
the key pointer I can give you is to be nice to the truck. my first ride was also an MJ (many years ago) and my biggest regret was that I didn't take care of it as well as I should have. you've got a real classic there. treat her well and she'll be good to you. :)
