I had the install done at Mr MCar in Farmingdale, NJ. He ordered the part from Dave and installed it and 4 mudflaps which I supplied. The tab was less than $150 with the CDV. He was recommended by Zeckhausen, and I give him high approval. It took me longer to drive there from NYC than the car was on the lift.
