73-80 rotors, calipers, pads, bearings and seals, absolutely. They are direct interchange.

You can also use the 73-80 brake hoses and lines too. Beware though, that you need to use all or none of the brake hoses and lines. The 73-80 brake lines are much different than 72 and earlier. The prop valve mounts down under the radiator. But, if you remove all of the lines from the master cylinder to the wheels, they will all bolt on.

My current 63 has every inch of factory 80 model brake lines and hoses under it.
