You can upgrade the 8.25 drum brakes with a D35 disc brake setup. In order to do this upgrade, you will need longer flange bolts and to dremel out the inner diameter of the brake backing plate to fit over the 8.25's 3" tube. some use the KJ e-brake cables which are longer and don't require modification.
