SSBC rear disc brake help!!!

I just went thru this with my car. We installed their set -up back in 2004.The SSBC caliper parking brake ratchet failed. The replacement is Ford T-bird,I ordered it for a 1993. Got the replacement at AutoZone only difference is where the park brake cable attaches at the park brake arm.I had to use a small cable clamp as the arm has a large attachment compared to the SSBC. Mine are mounted both to the rear.
