I have a '96 C1500 w/Vortec 5.7L. Where the air intake and the resonator (that is what this is called right?) fit to the top of the throttle body there is a 4" gasket. Previous owner had gooped it all up with silicone to try to seal it. GM says part is discontinued from them. It's pretty banged up, and I'm sure it leaks air like crazy. I've been very unsuccessful in finding anything in local shops, online, etc. Does anyone have a resource for this thing? Or a suggested equivalent replacement? It is a metal-core ring with a rubber coating. See attached image.
