eh.. 800 bucks.. clean it up days worth of work..  gears  150 bucks plus another 100 for install kit..  brakes?  pads.. ok 40-50 bucks at kragen..  and calipers if you need to.. 100 bucks  driveline?  pinion conversion flange to keep yer yota stuff  150 bucks from high angle driveline..  brake lines? hmm.. depending on where you go.. i can get them made for 50 bucks theres 1400 bucks.. same as he paid for the fj80 front..  and i have a stronger axle to boot with more width for better stability.. not to mention it weighs more  so better unsprung weight to keep you on the ground... your idea is flawed.  and wheels?  you buy those regaurdless. Ive also done it before for customers.
