VBelt pulley layout

abodyjoe said
what year car are we talking about. water pump from a 69-down or 70-up.

don't just run what ya have if it is not correct. any pics of what you have?

It's a 70-up (73 Duster and someone swapped in a 360, not sure when).
Part # on the waterpump is 2951571.
Pictures attached.

How free should this impeller spin when it's off the block? If I give it a finger twist it turns but stops almost immediately.

Thank you for help :)
