FYI, 35x15.5 SX's are frekin nasty tires(if you let them sit for a few days you dont even need a parking brake, why? bc they arent round! <img src="/forums/images/graemlins/lol.gif" alt="" />). anyway, i remember seeing this 4runner on ebay, of course they left out everything you have described. i like your future list of mods a lot, it will be very functional. change the rear springs, cross-over, 35's and 5.29's with a rear locker is a great list. you will have a great DD/trail toy. my $.02
oh ps, look into the chevy rear spring swap.
