Something i noticed is everybody keeps throwing out different year rotors and such, i just used the same rotor as the front of my truck,'89 Burb, i did find out too, that you need to make sure the brackets you get for the rear are cut for either the Chevy calipers, or Caddy calipers, as they are different with the mounting bolt spacing, and rotor width, i had both sets of calipers, and could only use the Chevy calipers. oh well though, works great, also make sure you do the "anti-squeel" stuff when you install the equipment, i didn't at first, and MAAAAN did they ever squeel.
There are probably better and less expensive brake hoses,,but i just used the fronts (listing) off the '89 Burb, there is alittle more metal line than i would like, but custom ones will be made at a later date.
