1961 Chevy Impala Bumper Jack HookThis 1961 Chevy Impala Bumper Jack Hook is a reproduction of the original hook. The primary difference between the bumper jack years is the hook. Now you can upgrade any vintage bumper jack with the proper jack hook at a fraction of the cost. Keep in mind most vintage jacks are more for show than use since GM did not design these properly. We recommend using a modern jack for safety reasons and to prevent any damage to your vehicle.
