NOTE: Make sure you position the adapters correctly. 240Z and Early 260Z owners should receive four 6″ adapters. Late 260Z & 280Z owners should receive two 6″ adapters for the front and two 9″ adapters for the rear. You’ll be able to weld directly to the hub, BUT DOUBLE CHECK YOUR LENGTH AND DESIRED ADJUSTMENT RANGE! The strut should be threaded into the adapter at least 1.5″-2.0″ for strength and stability. MAKE SURE YOUR ADAPTERS ARE THE CORRECT HEIGHT for the stance you want to achieve.
