Caliper Mounts

[rallyvan]

Can any one confirm if the caliper mounts for the alloy Girlock mounts are asymmetrical? I managed to loose the passenger's side unit during the rebuild process and have sourced a new mount. When I sourced the new mount I specifically asked for the passenger's side unit. Before I contact supplier I'd like to confirm that the mounts have a specific to the driver's and passenger's side.

Arm and ball joint assembly (stub axle) are different left to right.
Callipers are different left to right.
Hub and Disc are the same left and right.

At least this is how the parts manual reads.
