Zack thanks for the pic of Ricks install. Larry, I think it's going to
be easier to do the firewall shelf. I just spent 60 minutes in the
garage and bent up some .032" and riveted it into a decent 'shelf'. I've
already got 4 bolts that hold the voltage regulators to the inside of
the firewall that I'll use to attach this to. One thing I didn't account
for is the slight forward cant of the upper part of the firewall so
there is a bit of a tilt to the shelf that I'll have to take out with
some shims/standoffs. The cable/antenna runs for the cabin top install
are problematic for me.

Have you considered mounting them under the cabin top, inside the
Accuracy Avionics overhead console? I know there are two layers of
fiberglass and a core, but that shouldn't interfere with the signals.
(in my non expert opinion). Any thoughts?
