      Really nice valve cover! Much better than the stock plastic junk. With a small amount of modification this val ve cover should last the life of my Jeep.

      Will not fit 87 and newer YJ

      Despite what extreme terrains discripstion shows this does not fit 87 and newer, surprisingly enough it's on the first page of the instructions provided. If I had an 86 or older 4.2 I would definitely purchase its is a nice looking cover. That being said I am still waiting on extreme terrains to send me a return label.
