I am begining to believe that you can't buy any reproduction sheet metal that is even close to the right size. This piece measures 41 7/8" from frame rail flange to flange. The correct dimension should be 41 1/4" . In the following pictures you can see how i cut the 5/8" from the center and rejoined the pieces.
