Suspension and brakes are intertwined and are usually done together in restos/rebuilds like you are doing to your RR. While you have it all apart, convert the front brakes to disc. It can be done with junk yard or auto parts store parts, so the costs are not high and you can keep it all Mopar. The rears can stay drum, no problem. But changing the fronts to disc will save you a lot of grief without costing an arm and a leg and takes no modifications to the vehicle.

And convert the brake system from DOT 3 to silicone DOT 5.
