i have one lying in store somewhere....lemme go and check its number....
by the way, when last time i bought a bearing, the packing said Mitsubishi Lancer on it. So maybe lancer ka bearing bhi chal jata ho spectra mein.
why dont you take the bearing out from the hub and take it to bearing shop for the reference with you. I always take the faulty part with me to the shops when i am buying new parts. banda dono ko match kr leta hai udher hi....warna akser shopkeepers ko bhi pata nahi hota k spectra k parts kis kisam k hote hein.
