Are you talking about the weird looking rods on either side of the cab? If so, they are the remnants of the bolts that go through the wood blocks that hold up the bed. I cut them out this morning. If you were talking about something else, I'm not sure what and you'll have to tell me. At this point, the only thing I'm not sure about are the wood blocks with the angled fronts that are still bolted to the frame. I just haven't gotten to researching them yet. Thanks for looking and asking!
