I have an 2003 econoline EB with Aluminess rear bumper with tire and box swing outs. The metal strap that mounts the upper part of swing out to upper rear door hinge cracked on tire side. Looks to be part number short 350175 and long 350175.1. I can't find the difference online between the two. Aluminess email was answered with only the short strap in stock and no explanation on the difference. Long story is I'm on an extended road trip and need to get it shipped somewhere and can't wait for a back order. Other option would be a fab shop around south AZ. Thanks
