Outer Ring of Magazine not Secure

[Biggym]

I am in need of the small Nut and Flat Head Screw that secures the front outer ring of the magazine to the bottom section of coin drop chute. The small nut is visible, the screw is not. The threads on my nut/screw are bad and they will not tighten causing a coin (Quarter) to jam against the point of the outer rim. To get to the flat head screw it looks like I will need to bend or remove a magazine coin slot(s). Are they removable?
