The guy who owned the 49 GMC 1/2 ton I bought, sort of turned it in a 3/4 by adding more leaves. I want to take it back to the standard number of leaves. Also, I have a friend that owns a spring factory that can, either make new or repair mine, but I'm looking for some sort of spec (spring coeficient, a curve load/deformation)so he can make the repair.
Thanks
