ok heres my issue- Using rancho lift springs that i gut used, not sure what year they are from. Thinking all the bushing were the same I wnet down to Summit and picked some up. Problem is that the bushings are 1/2" too wide for the springs. So I searched all over and cant find the right part number or application for spring bushings that will work. The units I got have a 1/4" "lip", the parts that goes against the outside of the spring. The ones I took out have a 1/2" lip. I am looking for the energy suspension part number or spring/year that these bushings were in. Anyone know which bushings to get?? Thanks!!
