Just doing some fiberglass work on the rusted out portions directly behind the wheel on the rear bumper. A piece (previous repair) was missing, and another completely rusted. So shape has been retained, but now im wondering what this part is even called, so i can get some specific details im speaking of.

I dont have my digi around till i go home again, in a few days.. just so I'm clear... It's on the drivers side,with the bumper pulled down, that metal, which the bumper clips into, (rear bumper) . it is not the fender. btw 92 Accord 2dr EX-R (canadian)

 

Like anything shown on here?
