Silent thunder exhaust flaps

I have a 89 272 sr1 with twin 454s with bravos. I need some help tho. Does anyone know where I can find the exhaust flaps that belong where the tail pipes connect into the silent thunder platform between the hull and platform. They appear to be 4in round flappers. Anyone ever replace having trouble finding them. Help would be appreciated thanks guys.

Bought them already from cpperformance and they are the wrong ones. Those are more oval instead of round.
