I'm getting ready to order a few misc items from McMaster-Carr and need to get a length of the wing root seal material as well. If I can through it in with this order, it will save a single item order from Van's. Does anyone know if McMaster has this seal material and can tell me the number? 
I've searched the catalog but have not come up with a definitive item- a couple appear close.
