I have no idea how it compares to an XJ in length, mounting, flares, or anything. I used a stock Dakota line. plenty longer than stock MJ. other guys have used other fullsize trucks' lines.
1: can't say for sure since I haven't seen the work. it's possible that a later block was put in and adapted to the Renix electronics/wiring and that's what they're talking about. It's a fairly common swap. pics would help. I would find the computer and see what's stamped on it.
2: most everything got better with time. the later horseshoe intakes flow air better than the 80s stuff.
3: a complete XJ donor. most everything will need to be changed. the 2 systems are very similar in overall design, but they share very little in parts and wires.
love the look!
just be careful with the XJ shackles if the truck is up on a lift. if a shackle is too short, there is the possibility of it inverting and going the wrong direction.
they are roughly the same size. tires that are sold with an inch designation are notorious for being a bit smaller than the number states (aka 30"ers are likely 29.5 on a good day) and the metric tires calculate out to being about 29x9.3".
peruse the Epic tech forum to get ideas of the paths you can take. Be prepared to kiss the rest of your drivetrain and your wallet goodbye. oh, and do not skimp on cooling.
it appears they bypassed the rear prop valve. makes sense considering the disk brakes.
front bumpstop is missing and there's a spacer puck inside the bottom of the coils that can be removed once you have a bumpstop again.
your leafpacks are... different from each other. not sure what's going on there. almost looks like a couple of individual leafs were installed... backwards?
the rear lower shock mounts look to be from the Explorer that donated its 8.8.
is that some sort of spacer-bracket fabbed to lower the factory skid plate up front?
WJ lower arms have a bend in them and will help with clearancing bigger tires. they are factory MJ length and just need the steel bushings trimmed a bit.
I'm a big fan of Samsung's Active series of phones. I simply cannot be trusted with a fragile device.
don't forget the used market when looking for a phone. I've acquired several phones off ebay (for friends and family too).
hard to say. what did they use to lift the truck? it could be anything from just shoving coils under the truck, to a full kit with arms, brakelines and a new track bar.
I know, right? proof that we all start at the bottom rung of the knowledge ladder. I learned my lesson and thankfully didn't lose my engine that weekend
when in doubt, search youtube for battery removal instructions. all batteries are removable in some way. I had to buy a special tool (cost maybe $2 on ebay) for my parents' old iphones.
