Hi,
I had exactly the same roblem. the part number is: 97910194. Search for it on eBay. I got mine there. But remember, you would need to get a pop rivet gun as well to fix the rivets on the hinge/body holes. You can get the gun from eBay as well. The whole thing cost me less than £13 (including postage).
I hope this is helpful for you.
Good luck!
