How would you repair this?

[masters]

This is the bed I plan on using if I don't run into too many issues. So far the biggest thing I have found is behind the passenger side wheel and both wheel tubs need to be replaced. I am probably going to tear the bed down into each individual piece and get one piece finished at a time.



Any pros or cons to tearing a bed apart to repair?



This is the bottom of the back corner right behind the wheel. There is also a hole on each side of the wheel well where I'm assuming marker lights were once there and has been filled in with Bondo.



How would you repair this? Patch panel?
