I bought new front leaf springs from National Parts Depot a year ago for about $350 plus shipping. Raised front about an inch from where the sagging old ones were. I had to use adjustable camber bushings maxed out and was still about 3/4 degree over. The springs settle out over time and I should be getting closer to spec. Rotate tires more frequently for awhile. NPD has bushings for TTB pivots. You will need shackle bushings also. There is a thread in tech section showing R&R. Leafs come with bushings. If I had known the paint was such poor quality, I would have shot some better coating on, as the springs are now rust colored after one winter.
