I looking to see who has upgraded their carbs on 83-85 200X's. I want to know what kind of manifold you are using. How does it fit? Any Pics? I am unhappy with the finish of mine and want to make my own. I have a design in mind and want hear some of your ideas. I will be constructing mine out 6061AL with a groove for the original o-ring for sealing. Let me know I may build more.
