Attached are two photos of four what look like spacers or brackets. Does anyone have any idea what they are from? I have picked them up from somewhere in the past but not sure where or what they are for. They might have come with some Wunderlich upper crash bars that i purchased second hand but they don't appear in the instructions. They might not even be related to the GS but they look "bike like". I have no idea. Clue - they might have something to do with Wunderlich lower crash bars but i have BMW ones. Does anyone know? Thanks in advance.
