Help! Can’t find part for hawk 250!

[Desuboi941]

So I’m here trying to fix my vacuum leak with the gasket and spacer I recieved today to realize it’s the one between manifold and carb… so they were too small and wouldn’t work. I’ve tried to find these all over and cannot I’m wondering if any of you have come across them before and can help. It’s the black spacer is all I need but they look the same just one is a black plastic piece and one is kind of a thinner cloth type gasket material. I’ve posted pictures here of where they would be located on the bike and the small gasket that goes on the spacer. https://files.fm/u/upsvn523k
