Below is my edited report to the list from about 3 years ago (Oct '98).  A
few updates:
*  H&R 29921 is now specified as the spring for both the V8 and the '92-'96
*  Eibach 1529.140 mentioned here is the "correct" version of these
springs, as originally released by Eibach, and not the erroneous group
purchase many encountered last year.
