I installed it not that long ago. Works perfect, but if you want a booster on it to make braking easier, you will have some work to do on the crossmember. I decided to try it without the booster first, so that is exactly the setup I used. That works with the MC that was linked earlier in this thread too.
Of course there is more to it than just the bracket. A dual MC works so that half of it is for the front, the other half for the back. You will need a proportioning valve to help with braking balance. If you look at the Brothers Truck Parts catalog, its in there and specifies the 1/2 ton.

Lots of work getting the brake lines set up, also I went with front disc brakes, so needed residual valves too.
