Kit: This kit is for 1973 - 78 axle with 1/2" studs on the end of the axle housing.
Details: All of our rear disc brake conversion kits use G.M. single piston calipers: These kits use D-154 Pads, have 7 Inch mounting screw spacing, and 1 Inch wide rotors. If you aren't worried about parking brakes they will work with the front calipers from a 78-83 Monte Carlo. Those looking for the e-brake setup you will need the rear calipers from a 79-85 El Dorado, Riviera, or Tornado along with the miscellaneous parts for the linkage You will also need to move your shock mount inboard 3/4 Inch. All kits require our stainless steel hoses to tie into the existing brake system. Custom hardware needed for the swap is included. This saves in the cost and allows you to locate the additional parts locally (parts store/bone yard.) The rotors are custom drilled pieces that are readily available for replacement if needed. An adjustable proportioning valve can help to achieve proper balance front to rear.
