I gotta get around to making something like that for the Liberty. the current plan of "wrapping the top of the door in screen and rolling down the window" works ok at night, but the entire concept makes opening the door during the day quite difficult because the screen keep falling down.
I've got buckets and yet still managed to spend more than my share of uncomfortable nights in the cab.
are those holes individually screened? or are they to keep out those Alaskan mosquitos?
those are the little plates that hold the studs. (those are XJ though, which are same in the front but different in the back)
I used five 1/4"-20 SS bolts (with fender washers) on each side to put the flares back onto my trailer. works just fine.
30 inchers and 235s will fit no problems.
31s can fit with some caveats (namely the stock rims aren't all the same, and 31" tires aren't all the exact same size) some tire rub is possible on the lower arms (can be fixed with WJ lower arms)
it is not advise to have a shaft extended due to the challenge of re-balancing. but you can have your ends lopped off and welded on to a new tube. all depends on what you've got in your area for a driveshaft shop.
don't even bother trying to cut out a floorpan. regardless of the ethical problems with hacking up a perfectly good body, it's simply not worth your time. the floors are held in by a million spot welds and you can get a perfectly good result from just flat sheetmetal. it's all going to be covered by carpet anyways.
it's been like 16 years now, but I still remember a point while building my 88, getting it on rims, and wondering if I may have screwed up and it'd never get out of the garage once on rubbers. it fit just fine, but it was closer than anticipated.
