Help! JC Higgins Model 20 12 gauge shell stop

[Apsco Epson]

I have a jc higgins model 20 12 ga that is having trouble keeping it's shells down. It takes 2 shells just fine but if you put anymore in the mag it ejects some or all of them if bumped or fired. Any insight into finding a replacement shell stop or even how to remove/replace the shell stop would be appreciated. As far as I can tell that must be what is causing the issue.

Thanks for the info , I will give Western Gun Parts a call. However the manual link you sent me does not show or explain how to remove the left hand shell stop.

A good schematic:

Looks like a tiny screw from the underside screws it against the bottom of receiver, perhaps a hard to see U-pin?

You were correct ! Small screw under receiver. Didn't see it at all! Got it out now. Wondering if the springs just gone weak. The stop doesn't look worn
