You may have already tried this, but go to Century Spring: http://tinyurl.com/26fyl5 If you know the ID and OD you know the wire diameter. If you know the wire diameter, ID, OD, length, number of coils, and material you should have determined the spring rate very closely. See if you can find it there. (It would be better to measure the wire diameter directly, if you can.) Guy Buchanan San Diego, CA K-IV 1200 / 582-C / Warp / 100% done, thanks mostly to Bob Ducar.
