Delco Jac Pac 175 Air Adjustable Shock System Installation into a 1968 Nova. Here are pictures and information of the installation of the Delco Jac Pac 175 Air Adjustable Shock System into my 1968 Nova. The system does not require any electrical connections for the pump or the under dash controller. The air line pressure is supplied by an under hood pump driven by engine vacuum. The underdash controller allows easy adjustment of the pressure to the shocks while driving. In another video I am putting together I will show the operation of it in the car.
