In 1984 Beech did a major upgrade to the panel on A-36 Bonanzas and B-58
Barons, getting rid of the high-mounted throttle quadrant and control column
boom and installing a conventional throttle quadrant and individual control
columns.

Beech didn't make this change to the F-33 Bonanza or the B-55 Baron.

Is anyone aware of an STC to fit the modern panel from a B-58 into a B-55?

If an STC doesn't currently exist is there any interest among F-33 Bonanza
or B-55 Baron owners in upgrading their current aircraft to the modern
panel?
