Well I got it apart. It wasn't that hard. I also removed the third member. As far as the auburn I found a deal on a brand new for 325.00. Had to act quick. Its the one mentioned above. I also found a 373 gear thru richmond gear for around 270.00. I assume that 3.70 down means that a 3.73 or 4.11 will work with the carrier. The stock was a open rear and doesn't have anything in it that resembles a carrier....just gears. I figured that for 325.00 I couldn't go wrong. I also wanted to step the gear up from the 3.36.
