I saw them sketched on a cocktail napkin at Somma's Pizza / Plum, PA a while back. They are for coil springs but the pivot points is what were needed. They will work A-OK for making a jig to fabricate the next step.....mock-up LCA arms.
Hot Rod night tonight and the Hemi Demon, HDK and the status of my Hemi build dominated the conversation tonight. The cocktail napkin conversation came up! Such a great memory for me.
