I have no plans to modify the front axle or brakes, I rebuilt all 6 wheel cylinders and the master cylinder and my brakes are great even without the Hydro-Vac hooked up. You let me know when your ready to get rid of the rear axle, it would be an upgrade from my single speed 7.20:1, I top out at 45 mph against the governor.
