John,

I have found that the factory spring codes in the GM parts listing are sometimes wrong, in so far as they don?t match what the car was built with. Because of that I have been recording the spring codes for ZR-1?s that have a known history. That is, original owner cars.

I have observed that several of each year ?92 to ?95 ZR-1?s all were built with rear spring RHY.
