Application This Part Fits Brake kit fits:1964-72 Chevelle, Malibu, El Camino1967-69 Camaro, Firebird1968-74 Nova, Ventura, Omega, ApolloIf you are going to use this kit on an A-Body Oldsmobile (Cutlass, 442), Pontiac (GTO, Lemans) or Buick (Skylark, GS), it will not directly bolt on to the original spindles even with grinding the .610" off the stud at the top. The lower bolt holes in the original spindles are 7/16" and the bracket and bolts 1/2". The upper bolt holes on the original spindles are 1/2" with the brackets and bolts being 5/8". You will need to replace or modify the spindles. Charts (PDF) Installation Tips Kit will not work with 14" wheels. Must be 15" wheels or larger. Kit must be used with original GM disc brake spindles or our new spindles # 910-34900, 910-35000. The difference between disc brake and drum brake spindles is at boss at the top where the bracket would mount. On drum brake spindles, this boss stuck out farther than disc brake spindles. Approximately .610" would have to be removed from this boss to work with these spindles. We recommend using brake booster/master cylinder combo 910-31978 with this front disc brake kit. Stock single reservoir 4-wheel drum brake master cylinders do not have the capacity to supply the proper amount of pressure for front disc brakes. Combo 910-31978 also includes an adjustable proportioning valve which is to be installed in the rear brake line circuit. The proportioning valve modulates pressure to the rear brakes which is necessary to prevent the rear brakes from locking up in an emergency stop situation.
