Peter,
Mine was an all metal rad.
I've no idea of its origin but it looked stock when I was working
with it.
As I've alluded to in the past, my hpe has a varied mixture of bits ranging
from 1979 to 1983.

I suspect this is the partially the result of complying with eccentric Australian regulations! I don't think that any other markets got a series 4 HPE with carbs for a start.
Alan,
My car had various emissions bits found on US models, such as multiple vent pipes on the fuel tank. I learnt that the Aussies had
very poor quality fuel at the time, hence their reluctance to have to deal with FI.
One interesting thing I've seen in pictures is that in one/some EU markets, the late hpe's apparently had carbs, as the tailgate
logo said 2000 without the IE script, which is what mine would have had originally.
But there again, who knows.
Nigel
