Hi Norman,

The only thing I have seen for this modification is an A65 clutch centre modified to take the Norton clutch.
I had a complete diaphragm clutch for A65 but I sold it last year and unfortunately I have not kept a photo of it.
It looked like the two parts had been machined to fit together and then brazed.  I had thought of using it but it was very heavy and it looked like more weight was outboard of the bearing than with a standard one.  In the end I could not see that much of an advantage over the BSA clutch.

Dave.
