Replacement parts

[MovinH2]

Anyone know a site where I can order the plastic piece that protects the seatbelt on the back of the 3rd row seat? I just got mine today in the mail and UPS broke it, along with smashing the number 1 Lever button and bending it to the side. I was able to unbend it and make it work again, but the button is gone. (Not a big deal with finding a replacement piece for that). But the plastic that protects the seat belt also protects the inside workings of the seat. Think I'd be able to order it from GM direct or find it somewhere else cheaper? I already searched EBAY with no luck.
