the belt size for the katana using the new style blower snout alternator bracket is dayco 5060775. I tried a 5060780 witch was a 1/2 inch longer.i felt it might be a little on the loose side. So then i tried a 5060772 witch is 3/4 inch shorter than the 780. That was too short so i ended at the 775.that one is as tight as i could get it. this is also for the 3.4 stock pulley.
I just wanted to add these belt numbers for future reference. Hopefully it will save someone several trips to the auto parts store.
