thanks Richard....... i got some research to do........
Good luck with that! :laugh: You can find very little on the 'net, and if Richard doesn't know, no one does.
Notice some of them are shown with the front rock guard, some not, pivoting forward subframe mount, vs. vertical mount on rubber, rear shocks inboard vs. outboard the upper mounts.
Your bike has a lot of desirable parts on it. Tank, front fender, throttle, brake lever, possibly the clutch, original tires, maybe a rebuildable original engine, seat hardware, carb support plate, rear brake hardware.
I can see the original frame plate. Located on the down tube, forward, just beneath the gas tank.
