This set can be used to upgrade just about any 84+ 90 Dodge, Chrysler, Plymouth automobile (Omni, Charger, Daytona. Laser, 600, Horizon, Shadow, Lebaron, etc.) with front disk brakes to the larger 60mm Kelsey Hayes single pin disk brake setup. The 60mm caliper was available only on the 84-90 Caravan/Voyager S-body platform with 14" wheels but is a direct bolt on upgrade for all the other K-car era cars. This upgrade is a direct bolt on and requires no other modifications when combined with the recommended 24mm master cylinder that is included with this set.
