Outer Limits 4x4 Board

Got a mate trying to fit BATC lower trailing arms to his GQ, when he fits them according to the sticker on them the stiffner bar on the top of the new arm hits on the lower trailing arm bracket on the diff, can some-one who has fitted these tell me wich way is up , we think that either the stiker to indicate the position was applied wrong or the arms are wrong.

Please help we want to go wheelin this weekend
