I bought 15 feet of Hehr 109-884-19 window gasket (Parkin Accessories number), they say it is for the Gasket for 6400 Series Vents and it is not what I needed. I paid $53 for the gasket, but would like it to go to a good National RV motor home owner. So if someone needs the gasket all I ask is for them to pay the shipping to their house, plus maybe send me a $3.50 McDonald's gift card and I can enjoy 2 Sausage Egg McMuffins when I mail the gaskets
