True- I went to my files and confirmed the Rallye Pack suspension cars had the heavy duty springs and sway bar and heavy duty shocks to go with the Commando 273. I owned an all original 65 with Commando-bought from original owner= a/c, p/s, p/b and no sway bar and 13" wheels. Probably the Commando was a stand alone option available separately like on the Valiants, as were tach, stripes, etc
