UPDATE: **SOLD** Was $400.
The bed extender seems longer than others I’ve seen. Might be custom.
“This is a vintage accessory to extend the cargo bed for a utility Jeep. It fits a CJ2, CJ3, CJ5, and Cj6. It installs easily. Just unbolt your tailgate, and bolt this in its place. No drilling is required. Your original tailgate moves to the end of the box extender.”
Post already deleted. Looks like part a Willy’s or Bantam trailer to me. The bed extender I have has straight sides.
Yeah, I’ve not seen one with sides like that either.
