datzenmike,
Up to Sept 66 the crank dog was used.

Does this have something to do with hand crank starting????

 

 

Must be.

The crank dog. Brittan's answer to Lucas electric starters.

The 1966 Datsun 520 was the last of the trucks with the hand crank feature.

The 1969 Nissan Patrol was the last Datsun/Nissan imported to the US with this feature.

Can anyone confirm fitment on the Moss Motors crank nut? Does it fit the Nissan J engines and 320 hand cranks?

I really doubt it. Japan was making efforts to standardize things by the mid '60s and were already changing threads. I could be wrong though I suspect the Datsun bolt is SAE.

I'm glad they kept the BSPT? British thread on the oil pressure senders.

We have different experiences with different BMC B Series engines. I purchased my crank dog from Kip Motors and the crank dog was certainly British Standard.  I did not spec and measure every other BMC B Series part, but deferred to Kip (owner) for his guidance on machining to fit the Datsun/Nissan J13 engine.

So you're confirming the thread as British Standard?

[zed1]

Yes.
