Re: [Chrysler300] Belts & Tran Lines - A little help please

I'm not where I can look, but I am pretty sure 
the inner, smaller pulley is for the PS.  The 
larger one/ones are for alternator and AC if you 
have it.  Without AC. my water pump pulley only 
has one groove and it is shared with the 
alternator.  That is actually how I recall most big blocks from the 60s on up.
