The dashboard is from an Alfa Romeo Duetto Spider. It's the metal painted dash, the chrome rimmed 3 gauges above the radio that are slightly angled towards the driver, and the wide padded edge along the bottom of the dash, that give it away.

The dashboard in the other link that you put up as an example, is indeed a Volkswagen: an early Type 3, so possible a Squareback, Notchback or Fastback, but since the link is indeed mentioning 66Squareback, I guess that's what it is...
