Hi Kurt
I'd say it's a 65 registered as a 66.
The U.S. and RHD did not have the steering lock so it must be a ROW.
The washer bag was mounted in the right inner fender 'til mid-65 when it was changed with chassis number 451 373. This corresponds with the mid-65 change to adjustable front strut mounts.
Well...that answered a few questions...
Are you still selling parts?
