Dyna Shock mount thread

Anyone what thread the top shock mount outer nut uses? I need to get some stainless nuts (not castle nuts like stock) in order to fit my ohlins shocks , and I appear to have mislaid my thread gauge!
Thanks
Steve

Steve,

The factory parts list will tell you - the 'Hardware Listing' in the back gives threads by part number.
