Hello, need help to identify the rivets that are on the EFX captain america shield. One is missing, it is the one on the hinge that holds the straps together on the upper side of the strap where you are suppose to put your hand. And i imagine it is like identifying a screw which is a bit of a can of worms for me. Can someone help? Can i put a new one in the hole? Should i use locktite? Help would be appreciated. Thank you.
