So I am trying to find a replacement panel for my 83 c10 but can't fine a reproduction anywhere. I cant get a pic to upload so i'm going to describe best I can. The outer area on the side of the firewall, in front of the doors, that bolts to the upper cowl where the front fenders bolt to in the rear. Hope that makes sense. I have checked all the major "stores / companies" for 73-87s and no luck, any help appreciated.
