Anyone have the FT rear hub carriers? Mine have small holes perpendicular to the Outer Hinge Pins. The holes are threaded as if for a grub screw. These holes are NOT on the plastic stock ones. Can't imagine wanting to attach it to the hinge pin. But what are the for, and are they supposed to be on the forward or rearward side of the car? The carriers are otherwise identical.

Carrier is upside down in the pic to better show the holes.
