Steve,

If the cowl spacing needs to be adjusted it might be less expensive to modify the cowling. =C2=A0

Thanks guys. Appreciated.

As far as the MT I=E2=80=99m looking at, I=E2=80=99ll need to= reduce the spinner diameter from 13 inch to 12 inch. Id this likely to present problems or substantive cost?

Steve

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:
