Hey midnite auto parts - contact Ray Stanley, Wheelwright, MA. He makes fantastic patch panels. Maybe he's got some patches for the rear bottom fenders for the 'burb. I know he can make anything. You might be able to make patches from the bottoms of pick up rear fenders, but check the curve of the fender in that area. The 'burb and panel truck rear fenders are a little more flat than the pick up truck rear fenders.
