Has anyone seen this oddball shock mount?

They came with the shocks years ago. It kept wide body shocks from rubbing the gas tank. They are getting hard to find. There are two styles. One uses the a spacer and one of the original stock washers. The other the washer is built on the spacer. I have some in a drawer and several here on shocks. Don't throw it away. Always guys looking for them. The shoulder nuts are what is hard to find.
