Trying to ID a heater box.

[Russ.W.]

G'day everyone. I own an Australian assembled RHD (right-hand drive) '67 Impala. Unfortunately, not all parts of RHD assembled Chev's are the same as on their US counterpart, and one of those parts is the heater box.

This same style box is used on 65-68 RHD Impala's, and I'm trying to figure out where it came from so I can buy the big replacement hose.

Done a bunch of Google image searches for every Impala between 63-68 to no avail. Done the same for local Holden cars during those years, and nada.

It'll be from another GM vehicle from around that time - not necessarily a full-size - could even be from a pickup. They kinda made a few cars in them years so it's kind of hard to think of them all.

RHD Impala's bodies/panels were made in the Canadian plant, so maybe it's from a Canadian GM car?

Can anybody help me out? Does anybody recognise it?









Thanks for your any and all help!

Cheers,
Russ
