As Zilla said, early models had a square swingarm.
Guy that had this for sale said it was a '70, but the frame number indicates it is a 1968. It came with a later year piston port DT1 motor and a complete RT1 motor.
This one has a later model rear wheel. Looks like a MX400 hub. The torque arm is homemade for sure!!
