Fabregas kicks ! Something ELSE to consider: when you put pressure on the handles of that new rivet gun, it's gonna squeeze those keys together, tighter'n a bullfrog's butt on a popsicle stick. Rotating the riveted keys apart? Nah. Not so much. Fuggedaboutit. Another trip to the nearest hardware store.....getcha some tiny brass washers that'll fit *semi-loosely* over the rivets, between the keys. *semi-loosely*, because that rivet 'tube is gonna swell a little,when the two parts get squoze together. The brass washers will allow the keys to rotate, but will last several lifetimes.
