try getting brake disc brake parts for a 70 340 a-body k/h disc brake they don't exist. seems any 68-72 a body never had disc brakes from the factory. autozone will tell you the same thing
I like to tell them what I want, then they ask me what car it`s for, what engine ,what my phone # is, etc., I tell them it`s for a 505" 68 barracuda, that really messes them up! :walk::walk:--------bob
