Looking for advice on disc brake purchase

There is another complete Kelsey - Hayes setup on Moparts, listed last month under Abody Parts for sale, by a seller named omnicrazy. That setup has almost everything brand new, the owner switched his Dart to the LBP setup, and is just unloading his SBP stuff. He asked somewhere in the $500 vicinity but that was quite negotiable.

You can purchase new SBP rotors from Centric (see Rock Auto) for reasonable prices (recently some members bought these rotors for $21/each!).

Calipers are also available from Centric in the ~ $60 each range...NAPA now sells rebuilt K-H calipers for ~$32 each!~

Hope this helps!
