Factory folding stock parts help

[partsguy]

New to these forums but have found tons of great info! I have a factory over the top "law enforcement only" folding stock. When shooting it at the range, the button that locks spring into open/closed position , spring, etc all popped out and got lost. I found the large button and spring, but couldn't find the other parts. Is there a parts diagram, part names, and best place to buy these parts? Also, best c-clip tool to use with this? Thanks in advance!
