Pulley questions

I never got pulleys with the motor so I'm starting from scratch.
I got a couple today, a lower 2 groove that lines up with the alternator and a single groove wp but the diameter is too big and the offset is wrong anyways...

From the center of the groove to wp face is 2.5"

What does the pulley I need look like?
