    It is a whole new bottom casting.
    The bottom casting is shorter.
    I am running two of the 2 inch models.
    Hey even if it ain't broke it's still fun to tinker with it.

    The original ones were cut down. They took a stock casting, cut 2" out of it, shortend the vertical shaft and welded it back together. They then added a nose cone.
