This is about the easiest kit to install as any of them out there. You pull your old drums off the front, have the hubs pressed out, remove the drum brake backing plates with brake parts, and reinstall starting with the Scarebird brackets. You don't have to take the front suspension apart or anything else weird. Since you reuse your old hubs, you can keep your 5 on 4" bolt pattern. Now for the downside. This kit uses Chevy calipers, rotors, Cadillac brake hoses, and requires a switch to Rallye wheels since the stock steelies won't clear the calipers. The kit rotors are 5 on 4 1/2" bolt pattern but they are dirt simple to redrill for 5 on 4" and that option is available from Scarebird. It all boils down to whether or not you can live with GM parts on your Mopar. I couldn't. That's why I have '75 Duster discs on my '66 Valiant.
