im looking for a cylinder head steady for my 1966 BSA A65Thunderbolt.
part number 68-4090. it appears to be same for all unit non-OIF Thunderbolts, Firebird Scramblers, and Royal Stars from 1962 through 1970.
there is a different part number for the 1969-1970 Lightning head steady, 82-9788, but i dont know why its different, or whether it might bolt right on.
here's a pitcher. number 24:
if youve got one you'll part with, please let me know
