I'm currently doing a soa, cutting the knuckles, disc brake conv, and gears and lockers on my 74 Fj40. I'd like some input about the whole shackle reversal, should I do it or just leave it alone. And If I do it, should I length the frame rails. It looks like nuclearmon's fj has this done. And should I invest in some long travel slip joints for the driveshafts, are they worth what downey wants for them? Is there somebody else who sells them for less? Thanks, Pete
