Just search google for V hook or Dixie cup hook. I bought this version from a different store for a few bucks less, but it seems they must have run out from the store I bought because I dont see them listed anymore. Here is an alternative shop that has them right now.

Unfortunately the holes don't quite match up with the premade holes on the pack, but the same screws work just fine. As you can see one of the holes can work while the second you can just put a washer on and tighten using the center opening as your screw hole. It tightens perfectly and is solid, just in case I added some glue on the nuts on the back side so they can't slip over time. If you really want overkill you could apply JB weld but it is completely unnecessary. It locks in the wand 100% better than the attached hook and best of all you don't have to do anything to your wands hook, keep it as is!
