To clarify what Dan posted, the parking brake pedal shaft doesn't connect to the frame at all, but to the cab in two places (see the attached pic where I circled in red.) These connections are totally independent of the frame. The inboard bracket buts up against the cab support cross-piece and bolts thru the floor with those two bolts circled. IIRC, there's also a bolt running front to back through the cross-piece, but that parts a little foggy in my mind.
