still after a pulley if you have any thanks

Sorry Im in CA USA i have a Fixed Fan and can change the Pump to fit either im going to use this Engine in a Morris Minor

sorry for some reason i dont get email showing response Im in California USA im building an Engine out of Parts and dont care which Pulley i need as i can just change the water pump to Suite , i think the short one would work with the Pump i have right now , im going to use the engine in a Morris minor

Thanks for the pics, makes it easier to understand the differences.
The so called short pulley was used with the water pump installed for factory A/C, IF I remember correctly 21010-H7227. where as the other one was used with the standard pump, 21010-H1027. As a pair they are completely interchangeable, just use the fan with the correct bolt spacing.
BTW all of this is useless not knowing where he is.

The short pulley (diameter about 107 mm) used with fixed-blade fan is
Nissan 21051-H9900
A new one sold on eBay last month. I believe this was only used in Canada and USA

The pulley (diameter about 103 mm) used with clutch fan is
Nissan 21051-H7200

* short pulley has the large hole
* long pulley has the small hole

A12, A14 or A15 could have been factory-fitted with either of these pulleys (depending on options)

First off, WHERE ARE YOU?. Next which pulley do you need, there are at least two different ones. One has a small center hole and the fan bolts directly on top of it, the other one is for fan clutch use and has a larger hole.
If your not sure, check the tech wiki.
I have both, somewhere.

wanted a water pump pulley to fit A14 B310 short pully
