Need help fixing a Rem 600

[Wrong Way]

I'm hoping someone has a parts diagram. I got a beautiful little 6mm with the vent-rib barrel from an estate. The "bolt retention" part is broken, and at some point someone inserted a machine screw to keep the bolt in. It works, but makes bolt removall a bit of a PITA. I need to see exactly what goes in there, so I can order the right parts.

TIA

Ryan
