The steering wheel in the picture above has had the plastic 'pads' removed. This seems to have been a reasonably common practice, but it would have had the pads when new.
See items 2 & 3 in the illustration.
The 8 track was a factory accessory & for the JDM Sunny Coupe, the heater, radio, tach, gearknob & clock were all options while the tach, heater & radio seem to have been standard in the Aussie spec Datsun 1000 Coupe.
For our overseas members, the 'eh' refered to in the previous post is a 1964 Holden, model EH.
