Need advise on non a/c pully's, taking off a/c pump

You need the same brackets for the alternator, however the A/C alternators have a double pulley,and the non-A/C engines have a single pulley.

You may need to replace the lower crank pulley with a double groove instead of a triple groove pulley. I'm not sure about the water pump pulley if it is different or not.

Mancini racing sells the pulleys for the crank, and water pump new. They also have single groove alternators.
