Help finding seat to seat rail torx bolt

[sdbmwcoding]

Anyone have any insight on what the part number is on this part here? Realoem does not list it at all for the E9X m3, it does list the nut when you search under the 335i but the torx bolt is nowhere to be found! Local bmw parts department was confused as well.

To clarify, this is not the torx bolt that bolts the seat rails down to the car. This is the torx bolt and nut that connect the seat to the actual seat railing.
