65 barracuda quarter panel.

I have a 65 Barracuda in need of a right (passenger) quarter panel. The patch panels I have found are not big enough to repair the damage. I have been unable to find a complete one for a cuda, howevere I found 66 valiant Quarter. Other than the obvious Rear window difference, anything else I should be aware of? And by the way if anyone has a Quarter panel for 65 cuda please let me know.
