hey im trying to find a company that makes aftermarket gaskets for the back end of my 4runner. when you take off the top the gasket is pretty worn so and they dont sell them anymore at the dealerships so i was wondering if anyone knows someplace were i can get one or do i have to just go out and get basic wheaterstripping and use that?

The "gasket" (weather stripping) used on a pickup fiberglass top will work. You can get them just about anywhere.
