You are bidding on a power steering rack for 67-69 Camaro and 68-73 nova. These racks are a direct bolt in replacements for your old steering system. You will need to purchase a steering shaft kit that you can get on EBay and supply line's. A friend has one of these racks in his 68 Camaro and it works great. The steering shaft is 11/16. This comes with all hardware needed to mount to your factory A arms and tie rods that connect to the steering arms. If not completely satisfied with the rack I will refund the purchase price. Not compatible with Pontiac 400 engine, only works with a LS1 if oil pan is notched or not stock. When installing hold rack in place then shove both bolts through frame at same time.
