Well, looking closely you have the cam housing also. I am not sure if you have enough space there to fit the nose ring. If you mount does not require nose ring I sugges not to install nose ring. Is the mount very old?

I've just bought it. Nothing to do during Winter time and that idea came to my mind. May be you right, just leave it how Hyde said - "Type A doesn't require a nose ring".
