They come in 2" and 5". They are made from solid aluminum. I can get them for ya or you can PM Thrusted Vector on the 4 stroke side of things. He can send one out to ya. They are a good design because you dont use longer bolts that tend to break. It uses stock bolts. I had to extend just my throttle cable, then rest of the cables were long enough for the 5 incher.
