hi, just bought a may registered 67 beetle. it has the sloping headlights, 4 stud wheels and disc breaks . what i would like to know did some models come with only 2 rubber knobs to the side of the radio as this is what i have, but have seen a lot with 3 which includes a hazard warning knob underneath the other 2. was this an optional extra.

My 67 1500 beetle was manufactured on the 19th April and only has two black knobs on either side. The birth certificate states it wasn't ordered with any extras.
