o yeah...right. first unibody SUV... nutz...
ok, quickie....does the black one still run?
if yes, then it's not toast by a long shot, you should know this by now...if it's tweaked a little, then so what?
the roof and front clip (and to not very much of an extent) are the only thing that look like they're bummed, so go nutz with some air shears and just drop another roof on...or find a cj-6 soft top and weld brackets onto it for that...would win some prizes for obscurity for sure!
2nd option, since the body swap is out of the question, take everything from the wrecked one, put it on/into the 90, 2 doors are way funner than 4
