A usable air cleaner assembly which should fit the Yamaha DT125 and DT175 from 1978 and 1979.  It has been repaired.  Broken mounting tab was replaced.  You will have to drill your own mounting hole to fit your model bike.  It does have scratches but no cracks that I could find.  Disregard the part number written on the part...it is wrong.  Correct one is 2A6-14411-01.
