For a 1966 mustang, should I get a 1' sway bar or a 1' 1/8 sway bar, does it matter?
as long as they are listed for a 66 mustang , then it will work. it really depends on what you do with your car. if you do everyday driving or down curvy roads then you can get the bigger/stiffer one. if you are a all out drag racer then you can take the front one off or get something like a steeda front drag sway bar. its not to big of a issue, i had my car three months before i seen that i didnt even have a rear sway bar, i put one on and really couldnt feel a diffrence
