Say's it's a 1967 van which is correct for an 'E' reg, but the dash is from a later model as is the Highwayman bodywork. Another interesting feature is that the window beside the rear door is on the wrong side! (need an anorack smiley)
They don't seen to stick out far enough to see past the bodywork:I
And relax
...which is the same criticism the Highwayman received back in the 60s when they had the original door mirrors fitted. Apparently, you couldn't see past the coachbuilt bodywork. [)]
