69 cuda disc brake parts

You have the highly desired Kelsey-Hayes 4-piston calipers and rotors. Rebuilt calipers are $$$. Look on rockauto.com The rotors used to be expensive (~$90 ea), but are now ~$25 from Centric. The downside is if you ever want to switch to an aftermarket disk setup like SSB or Wilwood, those adapt to either a 9" or 10" drum spindle.
