I bought an alternator, off a forum member on Monday, which was meant arrive yesterday - still not arrived today and I'm fucking   as I was meant to be heading away this afternoon to see family for the weekend, and now I have no car to do so.     Anyway, my cousin had a spare alternator in his Garage, from a corolla T Sport, which I thought may fit, but the alternators are different.     The voltage reg in my alternator has failed, so would the voltage reg from the T sport alternator fit my original alternator?      (Starlet Alternator is on the right, T sport alternator is on the left)             T Sport Alternator          Thanks
