I went out and looked under my 8N a little while ago. It's got the mounting bracket for a swinging drawbar,...doesn't look like it's ever had anything attached to it.
Most folks do not even realize the belly pin is there. They just pull from the flat multi point draw bar.
But the swinging draw bar is the originally designed pull point. It takes the wear and tear off of the lift arms.
The pin under the rear axle to retain the front of the swinging drawbar is a bit of a proprietary item. If it is missing, you will have to find one to use that style hitch. We always welded a piece of chain to the bottom of the pin and and tied it to the axle assembly.
