Bob, the repair area will only be a 1 3/4" by 1 3/4" square piece, maybe less, with the hole in the middle. It's really just the recessed area that has some
rot. I was hoping to just cut out this area from a trunk floor replacement piece. Or, I might just punch a hole in some sheet metal and work on making a recess. This repair patch will be very small. Jim, interesting observation. The hole on the passenger side is also in a recess and is solid so I know the recess area is correct for this car.
Thanks!
