Parting out two(2) 1967 Barracudas.

Hello, I know this may sound petty but when you need something you need it. Im looking for the special speaker/air vent mounting hardware. if you remove the speaker mounting plate you will find these. They slip into a slot in the dash frame. I've included a picture of one. If yours are there and you would like to sell me the set it would be appreciated. Let me know cost and shipping to 60491. Thanks
