The "wind stops" (metal frame, gasket, and thin screen) in the Ferrari 360/430 Spiders reduce the wind whipping in the cockpit of the car and add a nice distinctive touch. On some Spiders, the gaskets in the wind stops have deteriorated to the point of failure. This is rather unusual to see and I suspect that it's due to either some sort of detrimental treatment product being used (such as Armor All) to clean and shine them, or a material failure in some batches. I've made a number of sets of these gaskets as a learning experience and am offering them for sale. Some sets are better than others as I was learning how to make them. The defects are small bubbles and inclusions. If you need perfect, then please, buy the OEM frames. The better sets are being sold first. Price per set: $300 plus shipping. Each set includes the three gaskets and three sheets of screening material. If interested, please contact me at: jcoryat@usnaviguide.com Installing the gasket in the frame...
