B50 1971 Crank shaft nut 21-2066

Hi

Any one got the correct crankshaft nut alternator side - 5/8 Cycle 20 tpi for a B50 71 (21-2066)? Not sure if it is plain or with a shoulder to locate against the rotor?

N.B. parts book indicates thread is 5/8 unf but previous discussions have confirmed it is a cycle thread

The b50 crankshaft nut is the plain type Steve, its possible to put a 5/8" cycle tap through a 5/8" unf nut, this works a treat.
