The springs ran me $40 at the pick-n-pull, and there are plenty more there for the future, if I need them. Front mounts where $55, rear mounts $35 and shackles about $38. The ubolts cost me $25 and the shim about another $20. The longer brake line was $25, but is optional with choice of shock lengths. The welding should run in the $60 for those looking to do this.
However, I went through a previous set of front mounts. They where from Trail Gear, not as low profile and got messed up when I tried to remove them. I originally put the front hanger 11" forward but I didn't like where the tires sat in the fenders. I also had the rear hangers at 4" back and didn't like the shackle angle or the lack of lift I was geting. So I had to grind those off, and fortunately they where re-useable.
So far I have about 500miles on the springs. I also put the spare on and put an extra 100lbs in the back of bed to help settle the springs. I didn't notcie them come down any. They match my front setup perfectly, with just a tad bit of rake since the front is set just under 3". This is my front setup:
