US Car Tool Early A Body Frame Rail Connectors

Ratrod I do have a question when I was doing my mock up today and taking measurements is there a offset between the front frame rail and the rear rail? What I'm talking about where the front rail and trans cross member rail come together to form a T is that a straight shot back to the rear frame rail? Taking my measurements it looks like the a straight line from the back to the front rail I'd need to offset the rail to the outside of the T on the trans rail is this correct?
Thanks Aaron
