I need a hitch reciever with a tab on the side for a sway bar ball inorder to use a sway bar on my trailer. I have found them on the web, but i have about 3 extra recievers laying around now, if someone has one and could tell me what the lenght of the flat plate is i could make me one and not have to buy another reciever. Someone told me that the lenght from the edge of the reciever to the center of the ball hole was critical inorder for the sway bar to work correctly..
