Convertible Header Seal Retainer

My 1964 Valiant header seal retainer had a few rust-thrus, but still useable. I should be glad since a Modesto convertible which isn't quite as dry as the OC. Removed it years ago and treated the rust (wire-brush, Evapo-rust, phosphoric acid, paint). Got around to installing a new top, so browsing. Since none available, I suggest fixing yours. If you have a welder, you could add sheet-metal to span those 2 gaps to stiffen it, but probably useable as-is (after repaint) if you use extra glue on the new weatherstrip.
