79 Jimmy rear seat belt
 

Does anyone know where I can source a rear seat belt for a 79 Jimmy? I only need the outer, short male end on the drivers side. The one I currently have is pretty chewed up. Local scrap yards don't have any parts that old. I've been checking ebay with no luck. From what I've gathered, there are none available aftermarket. Here's a picture of the passenger side, this is what I'm looking for on the drivers side. Thanks
