need help identifying(sp) a gasket

Ok, here goes my wierd explanation of this gasket( I say weird because all the parts houses here cant figure it out). The gasket goes in between the block and that whole assembly where the oil filter screws into. I told this to the parts store and they said they could order it and the next day I got some little o-ring that goes between the filter and the assembly. So if anyone knows the proper name for it or if someone has a manual they can get the part number out of, I would greatly appreciate it.
