Lower longeron is straight over the wing and kicks up behind the wing. It also transitions from an I-Beam to a Tee shape (the inner flanges get cut off) at some point behind the wing. This is all from my memory though which is notoriously defective (just ask my wife), so don't build a real P-51 using this info.
