Update: Turns out the springs I had on this thing had been built up dramatically. The rears normally have only 9 or 10 leaves. Mine had 14. Fronts normally have 6. Mine had 7. No wonder I was able to carry over 4,000 lbs eek
Price I was quoted locally ("about" $1200)was for standard set of springs. Benz Spring in Oregon has hooked me up with replacements for what I had, plus new U-bolts and shakles, plus shipping to Southern California for $1,091 complete. They are building them now. I will let y'all know how it all works out.
BTW, if anyone would like to buy my old springs, they could probably be easily taken apart, cleaned up, friction discs and bushings installed and be perfectly fine. I will be posting in the stuff for sale section.
Take care and brush your hair...
