If u have time to shop, u can beat mancinis price a bunch, I did on ebay. You can also cut ur existing brake pedal pushrod in half, thread it and use a threaded coupling to put it back together, making it longer by the same amount as the thickness of the new adapter. I welded mine up 1/2" longer after adjusting the length, then trimmed it down in a lathe to make the coupling smaller and prettier. use the standard distribution block for manual brakes, works well , and doesn`t cost much.! 1987 dodge diplomat /2 bolt alum. master cyl.
