     Sounds like a good solution to moving the prop back on a pusher.
     Structurally better than bolting on a prop shaft extension.

     What do you charge for a longer shaft Tracy?

     BTW a stock bell housing may not be designed for prop gyro loads
     but they do take a beating in a car application. The rear motor
     mount is under the end of the transmission so the bell housing is
     designed to take a considerable bending load when the car hits a
     severe bump.

     Not only that they are high pressure die cast therefor they have
     much better strength psi wise than a sand casting. They are also
     much lighter in the bargain as the wall thickness can be as low
     as 2 mm or .090".

     For a tractor installation use of a stock bell housing  generally
     would make the engine assembly too long for most stock cowls.

     I have committed to do one more custom length shaft (for Kelly Troyer).  Sorry to all, but this is the last one I will do.  The time required to do this is simply not available.   Any
     future custom shafts will have to be done by the builder.
