Leaf Spring Codes
I've been searching for a front & rear leaf code chart and can't seem to find a comprehensive one anywhere. I'm working on an `87 Z52 in my shop right now with a butchered front spring and wanting to replace it and possibly increase the rate too and have access to lots of front and rear 84-87 springs but the dismantler didn't mark what particular year and optioned car they came from so I can only go by the codes on them. Anybody have a link to a good chart for this?

Give me an email and I can send codes too.

Thanks, I found that one but it doesn't show what the three letter code is for the specific spring just what options had what spring rates. Do you also have the letter codes too though?
