An update to this thread, i have been working on having these remanufactured for the moment in the later Font, Older font i will look at later, so far i have engineered the right display and tested a batch in all conditions and compaired vs old ones, i am at the point now where i am going through the process of having the middle and left done then they will go up for sale.

Oh wow great to know The1
Mine are looking a little sad. What plastic did holden use on these vn to vs commodores everything just cracks and breaks before you even take it apart lol

I assume you mean the faces of the gauges? I know they become very brittle. I believe it's polypropylene, wasn't made by Holden, VDO manufactured them. I personally knew the guy that was manager of manufacturing in VDO around the time these were made and back into the 80s.
Not at the time though, but in more recent years while we was working in another auto supply industry using similar tech. One of the VDO factories was in my town so we went down that rabbit hole during our many chats. The materials were often a poly-prop for the screen printed parts, acrylic for the light guides, the housing I can't recall, but I think it looks like ABS.

Unfortunately, nearly all polymers aren't stable long term, I mean years to decades, some for centuries like Bakelite, but most modern ones are decades only before spontaneous degradation occurs, nothing can escape entropy

Yes the housing cracks on nearly all of them now, i use a heat gun to around 400c and melt hot glue sticks as much as possible then bond around the screws.

new test LCD top old bottom.

Have now done heat and freezer tests no worries.

Wow cool bit of history.
Display looks good mate. Let us know a price when you get all 3 done maybe interested

The old one is quite grainy isn't it.
