The clamp came on the arm. Flowtech here in the Chicago Suburbs did it before I bought the arm. I've seen clamps like that in Jegs, Summit and other places like that, so I would think if you've got someone that can weld it, unless it's a chrome arm I'd go that route. I cant tell what kind of arm you've got, if it's a stock arm with extensions or a stretched arm, but either way you should be able to get one like that on there. Shoot me a picture of your arm and I or someone here on the board will give you the best suggestion.
