I found some 73 disc brake set up. I have a /6 drum and would like to upgrade. Can i use the control arms from the drums. I need your guy's help please.
I switched from drums to disc on my 1964 Valiant. I took disc setup from a 1975 Duster. I had to use the upper control arm from the 1975 Duster, but retained the lower control arm from the 1964 Valiant. This I beleive, is because of the different size balljoint for the disc spindle on the upper control arm. Mike
If the spindles and rotors you are swapping on are from a 71 (small bolt pattern, K-H 4-piston) then your existing control arms and upper ball joints will work. If you had 9" drums, you will need the appropriate disk lower ball joint.
