New headers but donut seal leaks

Hey guys I just installed a set of obx short headers and the little metal ring at the lower flange won't seal. It looks like the old flange might have rusted out a little. If it was softer it might seal. Is there a way to seal this with out a new flange like a donut gasket or something or maybe a set of odd 3 bolt flange gaskets

Re: New headers but donut seal leaks

Maybe use a liquid high temperature gasket on both sides of the original metal one...I'm surprised the headers didn't come with a replacement one. Mine did.
