I need help I just bought this tool box from my boss. I want to fix the big drawer but my snap on dealer he is not helping at all. He doesn’t have any idea what serie is. I’m thinking it’s a kr661 but I’m not sure. I also want to remover the drawers in the end cap so I can get to the lock. I have not idea how to do it. The end cap it has a Phillips screw from the inside in every single drawer. I tried to take it off and lift it but that didn’t work. Anything would help thanks.
