Hello,
There's a posting under the archive section that talks about putting a ford 9" under a tracker,he used stock rotors a saturn calipers so he could have e-brakes.Also if you used 4 door rotors on the back you could use Ford tarus SHO rear calipers.If you can find a set of 96 rear axles you don't need the KIT,they have the 5x5.5" studs made in"one peice" axles.
