At very front only severe rot under radiator brace . Piece is horizontal and called cross member sub frame or cross member brace. Has 7 large factory holes and 2 small holes on each side of the 7 factory holes. Don't know much about this piece but on my rig this piece is totally rotted out. Anyone ever replace this? Can I get the part from toyota?Who would I talk with about getting this section replaced? Thanks hope someone has suggestions.
