I ended up using a GM steering box and putting it where it was needed on the frame to match the steering stuff from the axle. All of mine uses stock steering components.... = cheap. It's not a high steer setup because it is not needed...

If you are looking for cheap, things like changing caster / pinion angle, high steer, SOA, are going to bomb your budget all up.

Welding to cast is tricky as im sure you know.. I would not want to do it.

Shackle reverse does a few things, but mainly it changes which direction your axle moves (towards or away from the transfer case) depending on if you are compressing the leafs, or unloading them. This needs to be taken into account when you start measuring for a driveshaft.

I really think SOA is going to end you up with way way too much lift, and be un necessary anyway.
