you should take the fender off, is it worse than this?

the tiny hole is just a gap in the stock sound material, i was able to leave most of it there and just take out the rust which is a much bigger hole.
that took me a while and tons of different pieces, but it was all patched with metal.

and thats not even the battery tray side of my car

i bet you classic center has just the rocker piece you need
