Thanks for all the info here. I did see that franks had the part I was looking for. Unfortunately, I need the left side only. Still searching for it, but feel confident I can find it in a salvage Camaro Firebird somewhere. Just to fill you in, I am repairing this section on a 69 Firebird 400 coupe. The car is pretty solid overall, but has a couple rust issues to be addressed. Starting a ground up restoration after the new year. Planning my work now and prepping by gathering needed parts. Thanks again guys, appreciate your knowledge. I'll post pics soon.
