Won't work in this case. The wedge bolt on a barend shifter is reversed with the flaired head toward the front of the bike and the exposed allen recess is actually in the end of the bolt facing the rear where a nut would normally go. So there is no "head" to pop off at that end. The OP's only possibility, if the Torx won't grab, is to drill through the bolt deep enough to get an EZ-Out to work.
