Yes, you need to match the pedal to the brake booster rod.
To change the pedal you just need to slide out the axle rod that the pedal swings on. It's very easy. On the right side of the rod is a small nut and bolt that holds it to the support under the dash. Remove the nut and bolt and that rod will slide right out. The pedal will drop to the floor.
