The third row seat's seatbelt retainer clip broke on my 2008 X5 4.8i tonight. The piece appears to be flimsy and I have wondered since day 1 when this would happen.

The plastic tab where the seatbelt clips to did not break. The part that broke is the plastic part to which the tab is attached to. This part is black with a steel spring attached to it.
Would appreciate info on where I may find replacement part online and how the repair is done.
