    Will the ring gear from a 12 bolt gov lock carrier fit onto a 12 bolt open carrier?

    Yes and No. Depends on the series that the open carrier is made for. If the open carrier and gov lock are both the same series then the ring gear will fit. If it is for a different series it will not fit.

    Each series covers a set range of gear ratio's. For 12 bolts IIRC 2.73, 3.08 & 3.40 are all the same series. 3.73, 4.10 & 4.56 are also the same series.
