I have been reading thru the posts trying to understand what type of spring is required for my car. Based on what I have calculated with the GM Spring Chart. I think my car, Z28, no special exhaust, no power steering, no spoilers, no RS would be a YF coded spring. Now the tricky part. Seems the Moog 6308s that everyone likes are not available. Springs in general seem to be hard to find. But I have a lead on an original used set. But I am trying to figure out how I would tell if they are the right ones for my car. So from the subject. Are there physical differences, markings other than the tags that would indicate which of the 3 options this used set might be?
Check out Detroit Spring.
What springs are in your car now? and what are the issues with them?
One of them is pretty bent. And they don't seem to have the number of winds of an original set. So I think they are a replacement set. I would post a pic but I currently have no photo hosting.
