You might be better off purchasing a "partial" quarter repair panel and cut off what you need. Be sure and check the outer wheel house where it meets the quarter panel. If the quarter is rusted, the outer wheel houses may be rusted as well.
I have a left side (driver's) quarter repair panel that I will sell at a loss - I decided to put full quarters on my hardtop. Not sure what shipping would be to ME. PM me if you are interested.
