I looked at Fastlane and they show 2 master cyl. available. The picture of the one from Teves doesn't show any hardware/seals. The one from Girling (Lucas) shows new mounting nuts and a seal for the mating surface of the master cyl. The online catalog does not list the large o-ring seperately. I guess I would have to get in touch with Phil on this one.
