I bought one from Numrich, but they haven't emailed it yet. The schematic Numrich has does not show the part I need to repair the revolver.

There is a broken small oval shaped part with two pin holes at the rear of the trigger that connects the trigger to firing pin striker and lever spring assembly. I need it, one of the two pins and a sear spring... Numrich has the correct trigger and lever assembly/firing pin striker, but as pictured there would be no way to connect them without this part and pins.

Anyone know what the connecter part is called?
Anyone have a good source besides Numrich for H&R parts? (the pistol is no longer in production)
