sup all,
i got some used comptechs, and they need new coil isolators for the rears. are urethane isolator sizes universal, or do i need to find specific ones for these springs? i'm assuming i'm gonna need specific ones. if so, where do i get them? also, the springs did not have the tags indicating each springs rate. so...how can I find out what each springs rate is so that i can distinguish the difference beetween the lefts and rights? do shops that do installs have equipment to determine rates? aight, i'll quit with the questions now. thanks, and here's a link to clarify what i'm getting at.
