Nate:
RE-READ the message and closely STUDY the photos that Bill (Subway Depot) provided. The "wing" extension that the sideframe attaches to with 2 SCREWS - has broken off the truck main block. He doesn't need any sideframe. He really needs a spare truck itself.,,,or to re-attach the broken "wing' more securely (ie: JB Weld, etc)
