Does anyone in the area have a parts car that they could let me cut the front driver's side floorboard out of? I know it's a long shot, but I was sad to lift my floormats and see cancer just eating away at my beloved 1965 4D Volvo Canadian's floor, mainly on the driver's side (it's pretty bad), you can see the street pretty good and it's not just a pinhole, try softball size.

Please let me know, otherwise let me know a good way to source these parts or some way to fix it so that it does not look like it was just patched... I am not body guy but this is the route I have been told to take (unless of course there is some other reasonable alternative).
