67 Camaro How would you tackle this?

[Steven's 72]

Thanks guys for the info, I posted the same question on Camaro.Net and got some feedback, I had to replace the driver side toe board and floor. The passenger side needed a little work around the toe board, then I got into the rocker and found that disaster. I will expose more of it during this weekend. Qaurters will need to be replaced as well.

Thanks again for the replies guys, I appreciate it...
