St. Louis Spring did me right. They re-arched my springs, rebuilt the pack, new pins and bushings, added a leaf. I think it was around $200 for the job. These were 2" wide springs I believe

I had a set of auxiliary spring packs made for my rear. 5 leafs each, 2 1/2" wide, about 3 1/2' long. Made at some place in Dayton Ohio I believe (before I found out about St. Louis spring) and it cost me a little over $600 plus shipping.
