This is a brand new Subframe bushing set for your 1967-1968 Camaro or Firebird! It includes all 12 bushings needed to replace all those old rotten bushings! Includes steel sleeves just like the GM pieces and they fit great with no modification. Worn out bushings will cause your car to sag in the middle and create and harsh ride and misalignment between the door/fender. Includes instructions that tell you where to put the bushings and torque specs, most other kits do not include these!
