Craig,
I don’t know if you got an answer to
your question, so if this is redundant just trash it.
The for W&B purposes, the weight shows
up where the weight is, independent of how it is supported. Therefore, for you
case, the weight is at 85 inches.
All the mounting methods does is drive the
forces on the mounting structure. Again for the case you gave there is a 4.16
ft-lb torque about the front panel when under no acceleration except gravity.
The will change as you accererate in the up/down driection. A three g climb
(vs. 1 g static load) will increas the torque to 12.5 ft-lbs.

question
Where
does the weight show up? At the FS of the panel, or at the
center
of mass of the radio?
Say
you had a 10 inch long, 10 lb radio and it was installed in a
panel
at FS 90. Will the weight show up at FS 90 or at FS 85?
FS 85
