71 R50/5 dual seat hinge?

[jdvorchak]

I am working on a 71 R50 and the dual seat has the front hinge but missing the rear. Funny because the allen head screws are still in the seat pan. So far I have not been able to see a parts fiche showing the bottom of the sea or those hinges. I guess they are called hinges. Look like a bent piece of rod welded to a triangular base. Anyone know of a source?
Thanks
John
