Joe,
Scott Swing has developed an alternative trim spring configuration
that solves the "radio clearance dilemma."
The new trim spring is slightly more progressive in its K-Factor,
which is nice - but it was specifically designed to have the smallest
possible "footprint" intruding into rear panel space.
I don't have any pictures or dimensions here at home, but if you're
interested, I can put something together for you when I get into the
office tomorrow to see if it will work for your setup.
