What mandrel needed?

Ordered a moroso 3 vane pump, wasnt sure on what mandrel to order? Have an ATI balancer, need pulleys for vacuum pump and alternator.

It will depend on the type of ATI balancer you have. If yours has a 3-bolt Chevy bolt pattern on the front and is flat with a Chevy center register, you can get a Chevy mandrel.
If it has a Ford front, with a center register that protrudes and a Ford bolt pattern, you can use a Ford type mandrel.
Moroso, Peterson, Jones and others make nice mandrels with various methods of pulley depth adjustment and retention. The Moroso mandrels are simple and durable....
The big factor is that everything needs to center accurately on the center hub of the balancer. Sometimes, the mixture of Ford crank trigger wheels, balancers with a Chevy front, and various pulleys and mandrels will find the need for custom adapter rings to center everything up nicely.
Call any time if you need help with the setup.
