I bought these, and haven't installed them. The brake pedal might work, but the gas pedal definitely won't. The dead pedal is too long. So right now they're in the box they came in, but they look cool. I wish I could use them.
A cut off wheel would be best. Air, or electric, air is better in my opinion. And you don't have to buy the 200$ ones, a $30 one will get the job done, won't last as long, but it will pay for its self. A guy in Tue body shop I work in buys the cheap ones they last a few months under constant use. When its gone he just buys a new one.
