New reproduction high-pressure liquid hose for all 1971-73 Ford Mustang & Mercury Cougar with factory air-conditioning. This is the front of two liquid hoses that connect together* between the filter-drier (mounted on the condenser at the front of the car) hose & fitting that connects the filter-drier (mounted on the condenser at the front of the car) and the expansion block (mounted on the evaporator fittings at the firewall). NOTE - The specialized 2-piece quick-disconnect assembly that connects the hose to the front liquid line will need to be re-used to enable for proper attaching. If yours is missing, we have it available separately.
