I judged a 68 at the MCA show in Florence SC, both kick panels had a rivet in the upper rear section. The owner did not know why the rivet was there. The other two judges had not ever seen a rivet in a kick panel. After the owner received his judging sheet, he found a Mustang salvage yard that had a rivet in both kick panels (His Pictures Attached). Has anyone ever seen this and why are they there?
