Here is my problem. I have a Civic with a JDM ITR motor/trans. The LSD broke. I bought a new LSD from a guy here and it doesn't match the one that was in my trans. I guess it's from an SiR trans. And he didnt send me the matching pinion with the new LSD. so.... now I need a single groove pinion to go with the single groove ring gear on the new LSD. Anyone know the best place to get the pinion? Is it in any other trans? Anyone know the part number?
