I have an old Wilton W-9-63 vise that I am just about to begin restoring not sure of the age. I believe I am missing the back plate where the 2 rods and screw go through. I believe the screw needs a cotter pin to keep in place. I reached out to Wilton to see if they have a diagram or sell parts. Does anyone have this vise and could post a picture? I am no machinist, so if I had to make a replacement could it be made out of wood?
