I'm getting ready to four-link an 76' Bronco. We are trying to deside on coils or coil-overs. Coils will be quik and easy, but do they require some type of sway-bar. Will the coil-overs as well require a rear or front sway-bar. Which of these ride better on the Bronco. We would like to avoid cutting into the body to mount the coil-overs.
