Gaston, I&#039;m not sure but only the last of the Fleetlines before they went to the Super line had the serial no. under the dash. What color are your rear wheels, red or green? Does the front frame have the cast on pads with tapped holes for mounting equipment? What is the engine casting no.? That may be of help, but I&#039;m not sure. If possible you may want to post a picture and someone may notice something that rings a bell. Good luck with the new toy.  oleblu
