i have a 68 with stock disc brakes. any idea if other year rotors and disc brake setups will bolt on to the stock spindles? my old brakes SEEM fine but the rotors look pretty crappy and the brake pads look low as well, thinking changing things might be the best way to go. Or any other options i might have?? i dont feel like taking my spindles and other suspension bits out. really just looking for an affordable rotor and brake pad upgrade and trying to see if stronger larger calipers and brake parts from other years and cars might just bolt on. are the stock 68 calipers pretty good and not worth upgrading much?
