Is there any other rear leaf springs that have the same distance from front eyelet to perch pin? I can make new rear mounts. I want to get some new rear leaf springs, but dont want to pay 160, per side. Mine have the s bend in them from spring wrap. Oh its a 63 with the mono leaf. Dont want to go to a 4 link, its a weekend toy and driver to and from work. Doesnt see any strip time, but it does get run hard.
