You didn't say what car, but if all 60's Ford leaf springs use the same bushings (and I think they do) I have a set I would sell cheap. I put a full set of poly bushings on my car and then put Cal-Tracs on it a month later. The Cal-Tracs use aluminum bushings so I removed the poly front bushings. I think they are in my garage, sealed in a plastic bag. If interested I can look for them a post a pic.
