My info says A06 Sports Group was 1969 only. A search of the 1969 Salesman's Pocket Guides found A06 offered only in Plymouth, not Dodge, and only for Barracuda, not Belvedere, nor Fury, nor Valiant.

For Barracuda, the A06 listing says, E for extra cost, $50.75, available for notchback, fastback, convertible, not available with Cuda packages. Included were 3 items, Sport Steering Wheel (also called wood grained), Custom Sill Molding, and Rallye Instrument Panel (Trip Odometer, 150-mph Speedometer, Simulated Wood-grain Instrument Panel).

The Rallye Instrument Panel by itself was A62 for $6.30. So most of the extra cost was for the steering wheel and sill molding.

AFAIK the same Rallye Instrument Panel for Barracuda/Cuda was available for Dodge Dart but is not mentioned as an option in the 1969 Dart Salesman's Pocket Guide, which may mean it automatically came with some of the 6 Dart models, maybe the GT Sport, GT, or 340 Swinger.
