Great Price, Great Fit
Works just fine, on my car right now. Perfect fit, easy to install. You don't always have to pay the high prices auto parts stores charge. If you pay attention, and get the right part, Amazon is the place to purchase parts. Not only that, but your getting the same parts that other places hike up the price on.
