1970 B-body Package tray for rear defrost cars

Hi to you knowledgable mopar peeps. I am trying to locate a vendor for a rear package tray with one 6X9 opening, other side is Defroster mount, and has the slot for the vent near the rear window. If you know where I could find this item, please enlighten me, Thanks,

You will never find what you describe. There is never one from the factory with one cut out, always a pair

It will have two speaker slots and you will have to cut for the defrost Duct.

Thanks, Jamie from Mega Parts said the same thing.
