FINALLY! The correct rear flex hose for the 1970-73 Mercury Cougar. The Mustang rear steel line fitting is .323" whereas the Cougar fitting is .395".
If you have purchased a reproduction front to rear steel brake line, you will want to make sure whether you have the Mustang .323" or the Cougar .395" rear fitting as some vendors sell a "Cougar" bent steel line with a Mustang rear fitting. If you have the .323" fitting, you will need to purchase the Mustang flex hose (D1ZZ-2282-A, click here to view Mustang Flex Line) to install it.
Replaces Ford Part # D0WY-2282-A.
