Hi Butch,

    You asked about the how high the prop bolt lugs stood ABOVE  the surface
of the prop flange on Tracy's RD-1B flange.  The lugs stand a nominal 0.6"
above the surface of the flange.   I got a variance between 0.580 -06.1"
probably because they have never been torqued down and seated.  Also they
are cylindrical (mine on the Ross drive were more of a cone shape) with a
diameter of 0.625"
