Need to replace gaskets on storage doors

I have a 2007 Safari Simba and the rubber gaskets around the storage doors needs to be replaced. I have checked the local RV shops and they don't have it. Looking at the end of the gasket, it looks kind of like a W. Metal teeth on one side clamps the gasket to the metal of the storage wall. The other side of the W is basically the seal. Anyone know of any place to buy door seals? I need 120 ft or so to replace all of the seals after I clean up all the rust.
