Rumble Seat Floor Pan, 31 Cabriolet 68C

[Ed in Maine]

I've started repairs on the rumble pan. On the left and right rear corners of the pan, the corners have been bashed in with what could have been a ball peen hammer. The hammered in areas are virtually identical leading me to think that they may have been done at the factory. I can't remember what was in this area for bolts. Was this done to increase access to fasteners? Ed
