Oh god, wtf do I do with those, don't tell me they go on the sear pin...
Those are the model 80 safety parts. See Deadman's diagram.
The little tear drop part (lower part on the diagram aka Trigger Bar Lever) gets assembled on the same sear pin on the very right side of the sear/disconnector assembly and right side of the frame. Make note of the orientation! It's a little tricky to get them all aligned up. When you pull the trigger, the back of the trigger bow pushes on the arm which in turn pushes on the plunger lever.
The other small L shaped part (aka Plunger Lever) gets pinned above the trigger bar lever with the hammer pin. Again, note the orientation. This part pushes up on the firing pin plunger, allowing the firing pin to be engaged when the hammer is released.
If assembled correctly, when you pull the trigger, you should see the plunger lever lift upwards.
The first time I mucked around a model 80, I had the trigger bar lever installed incorrectly. The arm was too far backwards and would not engage the plunger lever.
Remember, never dry fire a field stripped 1911 unless you control the hammer so that it does not fall on the frame.
When you reassemble, make sure to depress the plunger lever down so that the slide can slide back into place. After assembly, run your safety checks. If all passes, stick a pencil all the way back into the barrel, #### the hammer and fire in a safe direction. The pencil should eject out of the barrel with some force. If it just jumps or falls out, you're assembled those two parts incorrectly. Strip it down and redo.
Fun stuff!
