Any idea what these holes are for on the passenger side of the frame by the hole for the idler arm bolts? Thanks in advance.

Hi AT,
I believe that's a re-inforcemnent in the frame rail to help stabilize the head of the carriage bolt.
Regards,
Alan

Alan is correct. The center hole (square) is sleeved so one doesn't crush the frame rails when installing the Idler bolt. the 3 surrounding dimples you see keep the sleeve in position
