double water pump pulley questions (1 Viewer)

[Ddraayer]

I'm trying to put power steering on my cruiser and am looking for a double water pump pulley. I bought one but the bolt patten doesn't match up to the stock water pump. Am I going to need to replace the water pump to match the new pulley I bought? or is there a double pulley somewhere out there with the same bolt pattern as my old single water pump pulley.
The cruiser is a 1972 fj40 with the stock F motor
Thanks to all.

Post up pictures of what you have...

x2 on the pics, I have a double pulley sitting in a box of stuff, I wonder if it is the same as what you have.

OK
I've never submitted photos so I hope I did this right.
The smaller pulley is the single pulley that was original, the larger pulley is the double pulley I bought trying to make this work but the bolt pattern to attach the double pulley is different. So does anyone have the pulley I need or what are my options?
Thanks

The double pulley you got is for the larger bolt pattern fan clutch.

You need a double pulley for small pattern direct drive fan. 68-74 F engine w/ air pump is the best bet. The 75-76 2F pulley will bolt up to the F WP, but the sheaves will not line up w/ the crank.

edit:
Oh look, here's the pulley on the bookcase...

This is what I have, I am not sure if it is the air pump one mentioned earlier or a later 2f model. The holes do line up with a F engine metal fan. If someone here has a measurement to tell the difference, than I would be happy to help you out.

The one I need measures approx 1" across on the middle hole, approx. 1.5" side to side on the mounting holes and 2" across on the mounting holes. Anyone have one?

I have one, see post #5.

You need to figure out what depth pump you have and what depth pulley is required to line up w/ the crank. If the original pulley in post #1 is the right depth, then you just need a pulley w/ the same depth (mounting surface to back of pulley), plus another sheave in front.

So, what is the depth of the original pulley that lines up w/ the crank?
