Is it really wise to position the compass so close to all that metalwork
and frantic electrical activity?
The reason for placing it high has more to do with minimising the
magnetic disturbance than ease of viewing.
It might be a good idea to hold the compass over the instrument panel
and power up all the eclectics and to verify any deviation - before
mounting it permanently.
Just a thought

I can thoroughly reccomend the SIRS compass but would suggest you mount
it
on top of the instrument panel (my version came with a dual fitting
option -
ie: suspended or otherwise). We tried ours in the suspended position but
it
didnt feel right -BTW it is possible to attach it to the centre of the
plexiglass screen (as in most automobiles - cars to the Brits) as it
comes
with a very sticky (AND PERMANENT) attachment pad.
IMHO the suspended option puts the compass well out of your line of
sight
(you have to look up to read it) and there is the risk of knocking it
when
you are getting in and out of the aircraft. Of course if you have a DI
then
you may not need to refer to it that often.
