Dan, I would just buy the new leaf springs from "Springs and Things". I thought that they were very reasonable. I usually torch off the "u-bolts" and front eye bolt, sometimes the shackles come apart easily. Sometimes I use a cutting wheel instead of the torch. "Springs and Things" had all the hardware to complete this job, and I had them send it to me. (I believe that they also sell new rear suspension "lateral links" for the Imperial, with new bushings installed) I don't remember for sure, but I thought that I paid around $300 for new springs, u-bolts, eye-bolts, shackles, and shipping. I was quoted about $500 locally for wholesale on springs alone! The job is actually fairly pleasant to do, if you are using new parts to put it back together. Good luck, Jeff 65 Imperial Crown convertible
