Steve,

If the cowl spacing needs to be adjusted it might be less expensive to modify the cowling.

Thanks guys. Appreciated.

As far as the MT I’m looking at, I’ll need to reduce the spinner diameter from 13 inch to 12 inch. Id this likely to present problems or substantive cost?

Some Hartzell constant speed props only have counterbores for 4 out of the 6 bushings. Perhaps Bobby can tell you whether the MT props do the same thing. For an example, see this link:
