Just tried installing a 3-screw trigger on my rifle, when I was taking the orginal trigger out, i lost the detention clamp that holds the trigger pin in place. Where do I find a couple of replacements. Its the little "C" shaped clip. and what the heck is the real name for this part. I have been trying to figure it out on Numrich's site for a few minutes and I am really frustrated.

thanks
