The correct part number has to be 11570637, as I bought a couple of them two weeks ago. The problem was that I couldn't find any of those screws at the local dealer. I had to order them and wait for them for almost a week, which is pretty frustrating. Someone actually told me that you could use the best bugle batten screws there as they fit perfectly, and they are much cheaper. My brother has actually done that, and it seems like they are working fine. However, I still think using the original part is much more reliable.
