Needed - panel below rear window to trunk.
 

Hello everyone,
I am new to this forum. I need help looking for the metal panel that the rear window sits on and to truck opening. Mine is rusted out. I have a 1969 Cutlass 2dr sedan/post car. Does anyone have this part or a lead on where I can get it? Or a decent one I can use sections? No one making reproductions.
Thanks.
