Looks like you are going to need to find the build date on your car. There is one hose listed for Dec 16 and older and one for Dec 17 and newer. You could always cheat and take your old hose to an industrial hydraulic shop and have one made. They will take your old tubing ends and make a new hose for 10-15 bucks. Sometimes that's the only way to get what you want.
