This kit includes both the upper and lower rear control arms designed to bolt a 1964-1972 GM A-Body 10-Bolt or 12-Bolt rear end into a 1978-1988 GM G-Body; this includes Monte Carlo, Malibu, El Camino, Regal, Grand National, Grand Prix and Cutlass. The upper control arms supplied with this kit are built at the correct angle to attach to the G-Body chassis as well as the A-Body rear end "ears". These control arms are a must any time this swap is being completed. Using factory upper control arms will cause drastic rear end bind and incorrect driveline angle, this leads to traction lose, vibrations and unsafe handling. The lower control arms are fixed length and center the rear end in the wheel wells, lower arms also feature grease-able Energy Suspension polyurethane bushings and reinforced sway bar holes.
