The Start of my questions, Inner fender repair

Hey I am start my 65 Barracuda and the inner fenders were cut out at some point for headers and I cannot find replacements, Mine have holes from just behind the top shock mount to about an inch front the fire wall and down to the top of frame, Do you guys know if the inner fenders they sell for 67- 74, Could I get the pieces I need out of those with the right bends? Or do I just have to build from scratch.
A picture would be nice..
