reading that others who installed the nst ud crank pulley, i didnt think i had to replace the belt. that, however was not the case in my install.

i have an 07 3dr yaris hatch w/o air, so there was just the alternator, waterpump and crank pulleys to go around...i had to buy a slightly shorter belt to be able to tension it.

the oem belt is 360mm and i had to buy a 355mm belt (after trying several other sizes first lol (310, 335, 342)

anyone else had this issue?

EDIT: a dozen years later, its a 36" belt to a 35.5" belt....wrong units, but likely right tail-end of part #
