Needed 74 dart swinger left quarter extension

Odd request looking for the upper left quarter where the roof skin meets the quarter panel I had quarters replaced and found large amount of rot that's unrepaiable. Looking for someone to cut out the area from Their donor car. I had purchased this already from another member on here and was screwed out of parts. Paid for it and never received anything. It would have to be cut into the trunk and left rear window area (rear deck) thanks for any help
