Grader Moldboard Snow Wing Bracket For Allis-Chalmers 45 "Roll Away" Moldboard. The AC Roll Away moldboard has a tighter radius near the bottom. The lowest bolt hole has a crack to the outside edge. The hinge pin bottom support needs built up. The snow wing hinge is not included, but the support brace moldboard bracket is. Pictures of a much newer wing show the concept.
