1970 Electra Trunk

Hi everyone, I need some advice regarding the repair of my trunk floor. As you can see I have some holes where the wheel well meets the trunk floor. The question is, do I fab up some patch panels ? I noticed that 1970 full size chev has patch panels available, but they are about $100 per side. Any opinions on this would be helpful. THe trunk is pretty solid with the acception of these corners.

Thanks

Have to put something over the frame and under the trunk floor to keep the level. Goran
