I just had my new Bilstien shocks delivered and when looking at the rear set i noticed that the flat portion of the top mount is in different places (facing different directions in relation to the bottom mounts) on both of them. Does anyone know if these can be turned with pliers or something without damaging them? If not is this to differentiate mounting side (although when i ordered i never spedified right and left)? Thanks for any input on this.
