Hi Jaycees, did you ever find out who made that heater plenium panel??
 

That looks like one made by my father at Classic Panels in Wollongong however he retired in about 2013 and sold all his tooling to Rare Spares including the twin cam arch flare lip tooling.
 
Unfortunately there wasn't enough demand for the Escort panels and the tooling was scrapped. I found this out too late as I would have like to purchased it, a lot of care had gone into the tooling and the panels they produced were excellent.
 
You could try Motorsport Tools.

You gotta wonder whats going thru some minds when they can scrap multi thousand dollar Tooling like they were empty Coke cans.
Sacrilege is the kindest word I can use but Im sure you all know what you'd call this sort of barbaric misbehaviour.
Too pig lazy to advertise it on Gumtree or just give it to the nearest Auto Enthusiast who wants it. Crazy !
Denying all future enthusiasts of new panels from good Tooling.
