What size belt with air pump eliminator kit?

[Oregon LC]

Air pump has been pulled for TLC's air pump eliminator kit. The factory length belt is a tad big, pulley has been adjusted all the way out. Does anyone know of a belt part number for a belt that slightly smaller?

I discovered that the air pump eliminator kit comes with a pulley that is almost half inch smaller diameter than the factory air pump. At this point I will be looking for a 4 1/2" v-drive pulley.
