New replacement sheet metal front frame rail for Datsun 240Z, 1970-73, left side only.  These front frame rail repair pieces are modeled after the originals with similar thickness of metal.   We made the gussets and the straight frame rail in two pieces because if you are keeping your original floor boards or replacing them the fitment will be a little different.  Main rail is 38.5" overall length.  Includes left side gusset and rail.  Made in USA.  *See our other listing for the right side.
