Need Help Finding Rear Quarter to Tail Panel metal extensions

[SgtLee511]

Im working on a 73 Duster, I need to replace the rear Quarter Panel to Tailight Panel, to lower trunk extension. It is the piece that attaches to all three and faces the rear of bumper. Where can I get these pieces. Thanks Eric
