Yeah, I'd make a emergency kit.
Small Tupperware container with the 2 bar, a spare 3 bar, 2sets of Allen's, a flathead a Phillips and replacement screws that go into the IAT2/BAR holes. Eventually I know I'm going to drop one of those little tiny bastard so I have two sets on the go..
Also keep the SCT in there as well. My kits double-sided sticky to the back rear of my trunk
