2 door, 1995, 4x4 Blazer

I was wondering where I can find a patch panel for the panel behind the rocker panel. the area is at the bottom of the rear side panel right behind the door. I am going to try to ad a pic so you know which one i am talking about. It has rusted out and i need to weld a new one on, but need to find a replacement if possible.
:eek2:
Since I cannot add a pic, I can e-mail it to u if you would like

Thank you, Tony
