I would go with a liberty 8.25 rear axle. Same MJ rim bolt pattern and a couple inches wider. plus disks.
edit: forgot to add the wj info. It's an aluminum 44a and is not a popular swap. Plus a 5on5 bolt pattern. In fact I can't think of a single example.
Front mudflaps are a highly underrated comfort item. I never took the doors off, but pre-flaps the spray off the tires would just obliterate any hope of using my side windows. Lol.
5 stars, would do flaps again.
mine wrapped pretty bad on uphill climbs. (SOA wth pretty worn out leafs)
with aftermarket flares, it should work with either a 4.5" SUA or a 6" SOA. keep in mind that, either way, long bumpstops are what will keep your tires out of the sheetmetal.
I'm running 4ohm speakers in my Liberty with the old XJ radio. in fact, I'm finding it difficult to even find 8ohm speakers that aren't either cheap paper crap (aka "OEM replacement") or mid range speakers designed to be a art of a bigger system.
pretty much anything that's not made of paper will be better than the original speakers. aside from that, most 5 1/4s fit the doors and tuck behind the factory grilles. but not all will, so keep in mind how much the speaker pokes out from the mounting surface.
don't wait for time to magically give you an opportunity, make it happen! gotta make time for the joys in life. (the driving part being the joy, not necessarily the trans install. lol)
