If you want to keep your small bolt pattern wheels (5 on 4"), the '69 parts are a direct bolt on. Make sure you grab everything between the upper ball joint and the lower control arm, including the lower ball joint. Parts for this setup are getting hard to find and pricey though. These are known as the Kelsey-Hayes discs and were used on A bodies from '65-'72. '73-'76 A body disc brakes are also a bolt on if you get the upper control arms along with the brakes/spindles and upper/lower ball joints. You can also use the brakes/spindles from a '76 up F,M,J body (Aspen/Volare, 5th Avenue/Diplomat) with '73-'76 A body upper control arms and upper/lower ball joints. These brakes are large bolt pattern (5 on 4.5") and will need wheels with the proper bolt circle. The calipers, rotors, and pads are much easier to find and much cheaper to buy. Either setup will also require a dual master cylinder and a proportioning valve. The brakes on my '66 Valiant came off a '75 Duster. Hope this helps.
