I forgot to ask about running without insulators. Those MOOG K6023 were a real bitch to get in. The ID is not large enough, I had to put a relief cut in the lip, even so the weight of the car finally pushed them in, but I haven't looked again to see if they bottomed out or the spring just slipped over the lip and now some of the pad is where the lip should be. I suppose I could save some height if I removed the pad, as I would like to have somewhat of a lip to keep the spring centered. I was thinking of cutting off the pad and taping the lip around the last coil to keep in place, to provide a squeek barrior so it is not metal on metal (spring on seat).
