Awhile back I had seen a quick and easy adapter plate. It was a round disc with a king pin mounted in the center on the bottom side of the disc. On the top side a 2-5/16 gooseneck ball. There was 2 handles to attach your chains of your gooseneck. I have been wracking my brain, nobody seems to know what I am trying to describe. This simply slides into your fifth wheel and allows you to move gooseneck trailers. There is nothing bolted to the trailer or the truck. Any help with this would surely be appreciated.
