id be surprised if it did,,,the crystals , 80 hp and upwards are totally different animals to the 70hp and smaller tractors.... having said that the brake master cylinders are the same,
ive had a 8011 and a 6711 for getting on 30 years and not found much else the same....
except the starter motors are different handed, the crystall one will fit the smaller tractors but the not the other way round.
