need this bracket inside the trunk

O.k., we are in the middle of replacing the quarter panels, trunk floor, trunk extensions on this Dart Sport and found a bracket missing in the trunk. I dont know what it is technically called, have not seen it in AMD or year one magazines but I need one. It will probably have to come from a car that is being parted out. Will need to be from a 73-76 Duster, Dart Sport. It is on the driver side and it runs from the trunk gutter down to the trunk extension. I have a pic of the one on the passenger side but someone failed to replace it when they did work on the driver side sometime back. Would like to get this bracket in one piece so would have to be cut out with some extra metal to keep it intact maybe with a reciprocal saw. Take a look at the pic of the right side and you can tell it is the bracket hanging down. I need the same bracket but on the driver side. Let me know if you have it and cost shipped to zip 41035.Thanks, Bill
