I have a set from BYC, u should be able to mount any mount on it. Basically its a flat plate to mount the air bag onto, u could just weld in your power ball also, or just trim it out and put it lower if need be. Probally if u are going to be stressing it out allot, put some bracket under the plate to reinforce it.
