The pics arent the best if some one would find some nice clear pics of a rear pick-up fender to post would be great.
http://www.stovebolt.com/gallery/knapp_gary_1949_1954.htm The panel van fender, from the wheel opening up the fender is very flat as the pick-up fender is very curved. I'm not talking about the part of the panel fender that bolts to the body I'm talking about the face of the fender. The overall shape isn't right and if it was they would be building steel panel van fenders buy just triming the steel pick-up fenders to shape
If you look in the eBay links forum there's a set of fiberglass ones for sale.
