Firewall cover plate for heater core seal to fit '72 Duster

Hey all,

After some 40 years of kicking this project around one of the bits missing is the rectangular metal plate that clamps the seal to the firewall around the heater hoses/core lines. Doesn't have to be mint as I have the tools to recondition it but of course it would be nice if it was intact and reconditionable.

Thanks

Ken
