Mopar Performance P4876658 111” Bolt on Frame Connectors
These have been out of production for a couple years now, this set is from the early 90s.
The original original box was gone and the paper that held the bolts and paperwork was torn, so I trashed them. They sat in a barn with not very great insulation since the early 90s surfaced rust but nothing major, Mopar shipped these raw steel. The hardware and instructions are in great shape.
