alright i'm talking about the front 2. one is considered front right and the other is considered front left, correct? the one that is harder to get to and connects by the radiator is which one, left or right? just tryin to figure this out real quick. thanks

 

The front right is near the fire wall. The front left is near the radiator (this one is harder to replace).
