I am looking to get a 3 series posi carrier for my differential and was told by a salesperson to stay away from Auburn Posi's because they can't be rebuilt and can't handle burnouts. Is this true or not. If anyone has either let me know how they are, or better yet if anyone has an Eaton for sale let me know. I would prefer an Eaton but they are expensive and hard to find. I am inclined to believe him because I see alot of the Auburns for sale cheaper and are usually unused. Any info would help.
