I seem to remember an aftermarket product for 1st Gen K/5s called Tuff-Hide (Tough-Hyde?) It was a kit of precut aluminum diamond tread skin peices for the lower body quarter panels. They looked tough indeed. I saw a write-up in "Chevy Truck Magazine" shortly before they got bought out by some corporate conglomerate and changed their title and editorial content to << (offshore) Squirt Truck Magazine >>, or something like that.The new management never answered my direct inquiry. So anyway, does anybody have a line on this product?
