Used Mark 30H mid section Driveshaft Housing tower.  Very good condition tower.  Has the original rubber style bushings the lower is NOS and the upper is used and shimmed, the gear case cover with screws.   The  mating surface where the gear foot bolts to the tower has been trued up to be parallel witht powwr head mating surface in out milling machine. We have other parts that can go with this such as the springs and the sterring pilot ask about price. No Cracks or welds.  We have added to our store a good used 30H gear case that we just rebuilt in December 2017.
