Long story short - I pulled the seats to get them recovered and this is what I found on the driver's side floor pan near the back firewall. I've never had to deal with this in other classic cars I have owned so I'm not sure what my options are. Is this where Restorartion Design comes in? What panel do you think will be needed to fix this?
This kind of repair is kind of outside the experience of most body shops in the Northern California Bay Area. Have any of you locals had good experience with someone who could do rust repairs?
