PAUL, Bill has indicated some doubt about the thrust line location so
we should not depend on it.  I am happy with it being on center
horizontally but the vertical position is not clear.  I guess it is
not indicated on the plans. It seems strange that such basic
information is not supplied by Lancair.   Jerry

It is probably equidistant from the rubber bushings on
the Lyc dynafocal mount. Measure up from the ground
to the bottom rubber bushings and then to the top
and split the difference. Does Bill have the cowl yet?
Measuring the cowl placed against a right angle wall
will do the same thing.
