Can CPU backplates be bought separately?

I purchsed a Noctua NH-D14 heatsink+fans CPU cooler for my socket 1155 CPU. However, I misplaced its backplate that fits on the back of the motheroard over the stock backplate. Is there any place where can buy a replacement? I don't think third-party backplates have to be specific to particular coolers, I guess all socket 1155 backplates are standard, as long as the bolt holes are aligned with the holes on the motherboard and it fits over the motherboard's backplate. I checked Maplin's website and unfortunately I don't see any CPU backplates listed.

Only one thing stopping me now from poceeding onto connecting all my components and building my computer, is this missing bl**dy backplate.

Thanks.

Yes they can be purchased separately. Ebay is your friend.
