Patch, or Replace inner fenders?

Here is the Barracuda I am doing now 69 383-S 4 speed car. As you can see I am also replacing the section to the firewall, it was cut and butchered that far back. Just so you know,,,the AMD pieces that they sell for the firewall to apron section fit excellent on the passenger side but do not fit at all on the driver side. They made mirror images of the part Left and right but they are not the same left to right. I cut a set from a donar car. In the back ground in a Dart Convertible I also had just finished the same repair on the inner fenders. Grrrrrr Hate fenderwell headers..lol
