i got manual brakes on my 71 duster
all the cool stuff you got
i went with a company called "scarebird" (i know, not a name that instills trust)
they designed a bracket that bolts to your 4 inch spindle
that is the only custom part in the set up
they then use mix of off the shelf parts, a brake hose from a eldorado, calipers from a chevy celibrity and rotors from a toyota of some sorts
you can buy the entire kit for just under $500 or just the brackets and source all the other part yourself (you do need to have the rotors drilled to 5X4 but they include a layover)
oh, and when i bought it, they didnt include studs with the kit, i dont know, they may do that now...but because of the thickness of the rotor, they suggest installing longer studs
i installed this setup on my duster several years ago and it works great
not modern day muscle great but definitely very day commuter safe
especially since i also upgraded the master cylinder to a raybestos MC36406
1960-72 Dodge, Plymouth "A" body, with 9" drums Wheel Kit
let me know if you want me to send you the installation instructions
