The Supercar Registry - 69 camaro lower rear valance patch?

Does anyone know if someone makes a patch panel for the outer rear panel for a 69 camaro? I have a car that some years ago had a 5" x 3" dent put in the lower drivers side rear valance. Whomever repaired it, swiss cheesed the area to pull the dent out the best they could and put bondo about 1/2" thick in some places to smooth it.
I really don't want to replace the whole rear pan just to fix that and would rather have a patch panel welded in. There is not rust or anything else wrong with it other than that shoddy repair job. The inner valance is fine as well. I have checked classic industries and ebay without success. TIA
