I am restoring a 69 Mach1 428 4spd that originally had 4 wheel manual drum brakes. I purchased a front end from a 70 mach1 with disc brakes and plan to install the spindles with new rotors and calipers. Does anyone know if I can use this set up without a power brake booster? What mastercylinder should I use? Also have seen conversion kits that require changing the brake pedal but am not sure why. Can I use my 69 pedal? I know that the 70 spindles require larger tie rod ends. Is there anything else I will have to change to complete this? Thanks for any help!
