I have a standard seat but I need a Crown Vic or Convertible seat for my Sunliner project, would like to buy just the seat backs or just the piece of the frame that has the notch in the corner. I could weld that piece into my standard seat to make it what I need. 

If you have a Sunliner or Crown Vic seat frame and wouldn't mind tracing the notched corner so I could reproduce it I would be grateful. 

Thanks..Mark
