65 Barracuda taillight bezel to body PLASTIC gasket.

Does anyone know if repro body gaskets/seals are available, specifically the black plastic piece that goes between the taillight bezel and the body on a 65 Barracuda. My fish is currently in the paintshop and I have everything to put it back together except these bits.

The ones that were on it are badly degraded and are pretty unusable.

Or if anyone has a pair they'd like to sell?
