I have an old Robush wood splitter. I need to find a new "head" for it. What I am calling the head is that flat plate that attaches to the cylinder and pushes the wood to the wedge. I have tried to find these on-line, but have not had much luck. I would like to get one with the bolt-on ears that keep the head from coming up off the i beam. Mine is shot and is getting dangerous to use.
