Hello from Michigan! I recently purchased my first square body project, and I'm running into a part issue already. I have a new driver's bed side, but I can't seem to find a passenger bed side anywhere! Everyone says they are on backorder and no one seems to know if/when they will be available. Anyone have any ideas? Part#'s I'm looking for are GM1757104 or 15628616. Any information would be helpful! Love the site, thx!!
