UMI Performance rear lower control arm hardware kit for 1959–1964 Chevrolet B‑Body includes new 5/8" Grade‑8 bolts, washers and lock nuts for installing lower rear control arms on classic B‑Body cars. The kit does not include new shock mount bolts—the factory shock bolts are reused—but it does supply new lock nuts for the shock mount bolt to complete a secure rear suspension installation.
