1969 Barracuda Doors

Hello everyone. I'm Eric in Northern Utah, thank you for the ad here. I am doing a rebuild on a '69 Barracuda notchback. Doing this car for a friend of mine. He has owned it since High School and wants to do a restomod on it. I need to track down the linkages that operate the door lock mechanism for the '69 Barracuda drivers door. Anyone have a lead on where a guy can get these pieces? Thank you in advance.
