    Rated 2 out of 5 by from Parts did not work! Part description was for the year,make, and model for my truck yet the brake lines going from the master cylinder to the proportioning valve were incorrect. I had to make my own which was difficult due to the tight bend that needs to be made. Overall I was not pleased that my $100 part had wrong lines.
