I have a question somewhat related to this thread...how do you accurately measure lift at the retainer with beehive springs? (retainer is too small to land the dial indicator on). I was told NHRA sticks a razor blade between the spring and retainer, but I tried that and the razor blade isn't rigid enough to be accurate.
