I just pulled my rear suspension so that I can complete the restoration on that area. The bushings are pretty spongy, and the bolts passing through them are pretty rusty, so I want to replace them. I checked the polyurethane websites I knew of (Prothane, Energy Suspension) and drew a blank for new poly bushings...does anyone have a source? I ordered new spring shackles from JCWhitney, and they come with new rubber bushings, so I'll let everyone know how those do. I still need to get new "U" bolts as some of mine are pretty rough. I need longer ones anyway since I eventually plan on trying lowering blocks.
