I have already installed a scout power steering box on my 40, and want to lengthen the frame rails and do the shackle reversal. I'm also doing a soa right now. My question is will the steering box be ok where its at, if I do the shackle reversal and lengthen the frame rails, like woody did? Thanks in advance
 
it depends on where you put the box . You can use this as a guide . the rivet hole on the side of the frame for the factory hanger is almost by like a 1/4 in. the center of the new bushing sleeve hole for the sr if you add 1.5 in. to the horns. if your scout box clears it should be o.k. , but more important I think you gonna have pitman arm clearance probs.
 
I'm in the process of doing the same thing - FJ60 springs in rear, frame extended 1.5" in front w/shackle reversal using frame mounted shackle and reversed 40 springs. I'm wondering if 1.) anyone has any pictures of this same setup (preferably a profile view) and 2.) how much, if any, fender trimming will be required. With the front axle that far forward, does it interfere with the front fenders during full compression? I'l be running 35" MTRs, spring over.

I don't want to hjack this thread, but thought it was a similar situation.

To aswer Cothran's Question, Yes The 35's will hit the fender right where the Turn signal lights attach.. I would say Dont Go that far forward.. My springs are reversed and i butted the stock hangers up against the end of my custom bumper.. I may end up moving the axel back by drilling new holes in the spring perches..

Here are some pictures of how mine ended up, and how the front hangers mounted up

Mine is Saginaw (GM), so i dont realy know how to answer the original question
 
I run FJ60 springs on the rear end of my FJ40, I moved the front spring hangers forward and the rear hanger back, it gave me ~4.5" extra wheelbase, exactly what I was attempting to do. I really like the longer spring in the rear, I think it has improved my ride immensely.
 
my shackle reversal is butted up against the end of the frame with stock 40 springs flipped around . and i did move the axle back by drilling a new hole in the perch . can see pic at car domain . to see how tire looks in front fender no close up of shackle reversal !.running 38.5's .also using the up front sag box .so don't know about clearance either .
