These are the belts to use if you are running an ATI Super Damper (part number: 918251) & Jay Racing Alternator Relocation Kit combo.
Power Steering/Water Pump - Belt: DAYCO 5040457 (Perfect fit)
OEM Style Alternator - Belt: DAYCO 5040340 (Tension adjustment bar is half way from full extension/adjustment)
It might be possible to fit the next size smaller belt (DAYCO 5040338) but I didn't test because I thought it would be too short.
I am about to do the GM/Saturn alt. swap so I will update accordingly.
