    301 is rated 4.8 out of 5 by 4.
    Rated 5 out of 5 by from Had to try I had to return this but it's not Jegs or Stewart's fault. I have a small block Mopar application that takes the same diameter. Problem was the outer flange needs to be flat to fit, this part has a small raised lip on it. If it was perfect flat I could've made use of a much better design. The Stant unit is going back in.
