Morning guys. I've got a 2005 cummins. I need a new alternator, and I'm wondering if the alternator off a 2007 with the decoupler pulley is interchangeable with my truck. I hate that belt chirp at shut-down. The 2 Bosch part numbers for the respective alt are AL6454N and AL6430N they look exactly the same to me with the exception of the pulley.
