My experience was very similar but different. When I brought my car to Shelby American for the GT/SC upgrade. When I was picking it up I mentioned to Bud that I was getting the dreaded lanyard rust and they hadn't noticed it. [Which was odd because I was in Colorado low humidity and the car never saw rain]. Anyway, Bud made a phone call to Scott Drake and I went over to their location and asked for the right person and was handed a set for no charge. Bud installed them while I waited.
So the ones they replaced were they the same material as the rusted ones?
