Putting disc brakes on a 70>

[qksilver]

depends on what is available in your area. It is easier to swap the whole axle but finding the same ratio might be a problem. I know the steering knuckle is different (caliper bracket), the brake lines and the rotor and hub. I am not sure on the spindle, wheel bearings, hubs and outer axle stubb.
A little bit of help but probably not enough. I have just swapped from the steering knuckle out complete or the whole axle.
