I have a problem with both of the running board splash aprons on my 1951 3600. The bracket at the rear of both has broken off. It is the bracket that was bonded to the apron on one end, and has a hole in the other end for bolting onto the truck. I have both of the brackets, but they look as though they were originally bonded to the apron with something. Does anyone know what that bonding method was or recommendations for bonding? Any advice on the exact location of these brackets when reattaching them?
