1971-1972 Master Chassis Bolt Kit, 396/454 Disc Brakes
1971–1972 Master Chassis Bolt Kits for Big Block (396/454) vehicles with Front Disc Brakes are comprehensive, OEM-correct fastener sets designed specifically for concours-level restorations or full frame-off builds.
Manufactured primarily by AMK Products, these kits feature factory-accurate head markings, thread pitches, and finishes (like black phosphate, zinc, or cadmium plating) to replicate exactly how these classic GM muscle cars rolled off the assembly line. Choosing a master kit over buying individual hardware typically saves restorers over 20% in overall hardware costs
