Here's the *budget* SAS from the research I have done so far.

Front axle hub to hub toyota 8" 4.3 or 4.1 ratio open diff 200
front axle rebuild kit 75
front axle high steer arms, tie rod, draglink, fj80 TRends 429
front leaves from isuzu or any other 50 something inch cheapones 100
toy front hanger (weld it on, minimal fab, setup for toy fr axle) 150
fr rotors from fj 80 vented 80
front calipers from IFS toyota 150
front lockright 200
front 27 spline longfield brifs 400
front shackles + bushings 150
front wheel bearings 80
f+r wheel spacers 200
rear axle toy IFS 150
rear rotors and calipers 200
welded rear diff 0
63 inch chevy springs 100
rear hangers and shackle kit 150
toy IFS steering box 75
all stainless brake lines 150
cheap shocks 200
total 3240

this is without regearing, and thsi setup will run 35s easy from what ive researched and 37s if you go really easy

add on 20% more for stuff like:
steering lines/fittings, brake hard lines, misc hardware and anything else I forgot.

I chose the toy box becuase it matches up with the aftermarket toy high steer kits available and it can easily be tapped (by yourself) for hydro assist in the future.

You could always forgo the locker and longfields, wait and buy the cromo 30 spline set for 635, then buy a locker and run 38s no problem.

You could say I like the toyota junk huh? I just like staying import based <img src="/forums/images/graemlins/smile.gif" alt="" />. Front and rear interchangeable third members, drop out design carry one spare 3rd and you are good to go.
