i bought a new (used) crank pulley for my 99 gsr because the original one was uneven. the seller told me it was from a gsr, but it's smaller than the original. it looks like a b16 pulley. since the pulley is smaller, the original alternator belt is a little too long. since its pretty worn anyway, i decided to get a new one. would a b16 altenator belt be the correct length? if not, is there one that would be?
