Hi guys! A little background, I bought this Jeep from my grandma over Christmas as a favor to her; it was my late grandpa's which he had bought original. It's a 4.0, 2wd, short bed, with somewhere in the neighborhood of 130k miles... we're not entirely sure since the odometer stopped working. So far I've done a ZJ booster and master, refreshed the PND switch, done chores like u-joints, injectors, some wiring cleanup, new batteries, and started converting it to 4x4 with parts harvested off of an '01 XJ; I'm currently going through a refresh of the D30 and hope to have that under the truck this Friday. I'm not really into off-roading/wheeling, so I am confident the D30 will be plenty for my needs.
All in all it's coming together pretty well, but there's a few things I am hoping to get some direction on.
Seats -- The original seats are in decent condition but lack lumbar, lateral, and thigh support (really any kind of support). I looked at the brackets and found that they're .... unique looking. I can't recall any seats that have anything similar to that, and the XJ seats I had didn't look like they were a direct bolt-in either. Am I pretty much resigned to adapting whatever seats I want to some fabricated seat rails?
Shackles -- I do not want to do a SOA, mostly because I want to do a Ford 8.8 at some point anyway. It looks like I can do some Chevy drop shackles, like these ones: http://www.roughcountry.com/lowering-shackles-rc0501.html Would those fit the bill, or do I need to source some for a specific year?
Polyurethane -- I've got a dude who's recommending I do NOT use poly anywhere in the Jeep, for risk of tearing mount points; he suggests that doing poly in my CA bushings or anywhere else will cause them to tear off. I'm looking for good road manners, so poly made sense to me, but if the mount points are too weak and need rubber to live, then I guess so be it.
Control arms -- The same guy I am talking to says that changing out CA's is pointless if I don't go with Curries. Is there any benefit to running something like the Rough Country (or similar) arms? The factory CA's look pretty frail, and look like they'd twist and deflect pretty easily under load.
NP242 vs. NP231 -- I like the idea of an NP242 for the pseudo-AWD/full-time option, but I've read that it's not very good, however most everyone talking about the NP242 not being very good are speaking in context of wheeling, which I don't do. If I wanted a solid 4-seasons driver, would the NP242 be a better option, or am I going to be just as well suited with the NP231? Note: I have the NP231 already, but I can source a 242 pretty easy; there's lots of Jeeps in JYards in Utah ;)
Picking it up, and how it sits now, and my never-done-always-a-project fun car:
