66 Barracuda options ?

There was a couple options
Basic - radio and mirrors
Sport - wood grain steering wheel, better wheel covers and white walls 7.00 x 13
Rallye Pack was suspension - thicker torsion bars, shocks and additional leafs in the springs, front sway bar
The formual s package included the rallye pack plus the 273 commando (235 hp) and tach (instead of performance gauge) 14x4.5 on 6.95 x 14

No dual exhaust- y exhaust to a single pipe

Also - the 273 commando could be ordered by itself

As a matter of fact, you could order every Formula S option seperate, not order the Rallye pack option, and still have a Formula S optioned car in a plain Jane wrapper, such as a Valiant! Part of the option list also included the 892-893 torsion bars!

And as stated above, no early Cuda, Dart, or Valiant had dual exhaust, the passenger side torsion bar crossmember wasn't even sectioned out for the pipe to go through! I make a converted trans crossmember that allows the passenger side pipe to pass through for those who wish to run dual exhaust! The 4 bbl cars did have an upgraded exhaust system over the 2 bbl cars, which Accurate Exhaust reproduces, but it is $900+ for the complete setup! The 4 bbl cars are actually tuned to run this system, and it has a cool sound due to the resonator at the rear end!!
