Frame Rail Ball Stud Pivot Reinforcement Bracket Dimensions

I'm looking for all the dimensions on the bracket that plug welds to the frame rail on the driver's side to reinforce the ball stud pivot for the z-bar. I've got a piece of 1/4" steel plate and I'm looking to make my own bracket. Thus, I'm looking for a list of the dimensions of this little piece. Or, if there are any nerdy engineers looking to help me out, I'd love to see a complete, dimensioned CAD drawing of the part!
