I will take some. But...what i did was cut out all the offending rust. I had a good 1/2 3/4 inch good metal at the bottom near the frame rail. What i did was fab the pieces por 15 the whole area. Tack welded the piece on the inside of engine bay. Tack weld the piece on the outside in the wheel well. Stich weld the whole thing. Suck the pieces together in the middle with rivets. Por15 again and then 3m seam sealer all around to seal the area from air and moisture.
Its not the prettiest fix in the world but this car gets tormented on the street and track. I can say that my repair is better strength wise than when it left the factory.
