Trivia: How much did the 440 option cost for a 1968 Roadrunner?

In 1968, the '440/375 HP' 'Super Commando' was only available in the;

Plymouth GTX
Dodge Coronet R/T
Dodge Charger R/T

The Plymouth GTX is sometimes listed as a Sport Satellite 'GTX' or Satellite 'GTX',
but it really is it's own car.

The 4-Speed 'Manual-Transmission' cars came through with a Dana-Rear and 3.54 Gears.

The A-727 Automatic-Transmission' cars came through with the 8 3/4" rear and 3.23 Sure-Grip.

The 3.55 Gear-Set was the only Dealer Offered Option for the 8 3/4".

Though, if you knew a Regional Zone Manager, you could 'special order' a set of 3.91's for the 8 3/4" Rear
for $94.

No Special Orders for the Dana.
