I feel dumb, my rear pulley bolts came loose and several are bent and fell out. I bought new bolts and am trying to see the best way to put them in, but there is not enough room with the frame in the way. 
Is there a tool that can be used for this? My only thought is to cut the hex bit down where it hits the frame.
