I bought the clamp and the bracket for my cart conversion kit. Works well so far, so it earns 5 stars. I wish more of the components of these carts were steel because I am always worried about stripping the aluminum parts, but that wasn't an issue. I noticed that the cart becomes very back-heavy and prone to tipping over when the scope and scope stand are mounted on it. While not a terrible problem if one is aware of it, it makes me wish there were some kind of wheel lock mechanism for the carts that could prevent this.
