Ok I'll come clean,
I used to own a rally prepared Opel Ascona (GM - Holden) in the UK. They used to be THE rally car prior to 4WD Quattro's took the scene by storm.
And my first car in Aus was a Holden Wagon (V6). I managed to rack up enough points to lose my licence in the first 6 months of being here. Good job I did'nt have my aussie licence then
Thats why I now drive a Ford
Sorry, back to the thread.
That heater control looks very much like the one found in an Austin Morris 1100 (Pre BL).
