Restoring a 65 fastback and need to replace a part but cannot find new or reproduction part. On 67 thru 69 it's called fastback rear upper panel brace. Also salvage search hasn't turned up one yet. It's a structual piece that is below the rear glass and is welded to quarter panels. It also serves to hang trunk lid hinges.

 

im looking but they might not make one, you might have to fabricate..
