Stan,
Here is a photo of my mounting of dual AHRS boxes on a bracket spanning the
longerons aft of the rear baggage compartment. Notice that the AHRS units
are inclined at the same angle as the panel. You can also see the brass
hardware using jam nuts to lock the hardware and a dab of indicating
lacquer on each. The bracket is attached to the longerons with SS
hardware. Although the SS hardware is slightly magnetic as indicated by
testing with a permanent magnet they don't appear to affect the indication
or operation of the AHRS units.
