Nose cones and differences

[scleburne]

Hey guys,
I've been trying to find a resource that explains the different nose cones and which can fit what but haven't been super successful.
Can someone point me in the right direction please?

Questions I have are:
Did only Premiers have twin headlights?
Is there/what are the differences between HJ/HX/HZ fronts? what about the twin head light models?
I see in some there is more radiator hanging down below the bumper, what designation are these?
Are they basically all interchangeable from HJ/HX/HZ?

Thanks!

HJ/HX/HZ Premier and Statesman along with HZ GTS, HX LE Monaro and Ambulance etc.
Grills were known as upper and lower where the lower was typically Statesman. Custom job back in the day used triple grill arrangement (typically with the centre cut out of the bumper). The centre section of the grill made by cutting modifying a sacrificial 2nd upper grill.

All are interchangeable HJ-HZ single light or twin light aprons and supports.

And HZ Sandman had twin head light front

Thasnks for the info. I really like the twin headlight front myself. Both of my vans are singles. I might keep my eye out for one.
