Great product and helpful video
This product worked exactly as hoped for. The price could not be beat by any of the other major auto parts retailers that I checked. The part arrived in a reasonable amount of time and the helpful installation video made the job of replacing the old part very easy. I will definitely be shopping with 1A auto again for my auto part needs.
