Mine just hooks onto the back of the torso armor. I have a super strong magnet under the armor that the metal latches onto when in position.Hey Moe how did you secure the backpack onto the actual torso armor? I see you have a piece of bent metal that you screwed onto the backpack and it is folded over to make a hook. But what does it hook onto and is that the only way you have it secured? Thank you
Maybe the picture below would better describe the position of the magnet:
In this picture, the blue square would represent the neodymium magnet I placed underneath. I used a couple of ones from old Hard Drives.
