The one I got from the US (72011GA220) is fully metal and a different size - unlike its horrid plastic tanked little brother here in Australia.
I went through the unpleasant task of removing the dash/heater in my second L Series and took it to a local fellow who managed to squeeze a Mitsubishi heater core into the box.
So if anyone can use a brand new, genuine heater core - thats apparently useless in local L Series - let me know
