Thank you to all who gave me advice and pointers on exracting my speedo and the dismantling of same.
I can see how the hidden screw in the bottom right of the dash timber would have been a huge problem and probably would have ended up in a breakage.
The job was a bit time consuming but very easy, thanks to you guys. Below are a few images as to what I found.
Facia easily removed. Note missing fuel gauge screws.
After disassembling speedo, found melted and baked hard grommets. The offending one had melted towards 6oclock, thus 99% covering the light path to the green filtered repeater on the speedo dial.
I constructed a new grommet from some very thin rubber and held in place with a Dad's favourite thing, a zip tie.
I was surprised to find out the whole dash is plywood.
The broken wire is the high beam indicator.
It just basically fell off.
A quick solder and all is well.
The finished result made me
Thank you for taking the time to respond and help me do a job I actually enjoyed doing.

Nice job well done.
It's strange the rubber "grommet" has melted as these warning lights are only on for short duration.
The blue filters that surround the speedo illuminating bulbs on my car had melted. I removed them. Since I had already fitted LEDs it was just a case of painting the LEDs with blue enamel paint of the correct shade. Result is a nice bright speedo gauge at night.

BTW - Was the rubber pad that sits on top of the steering column cover just resting there or was there a clip on your car.

Super job, nice to see the speedo digets all lined up, this one has not been clocked as so many others I see.

Thanks guys for the replies.
I actually enjoyed the job and it's quite an easy dash to work on.
Of interest the entire back of the speedo, wires globes speedo cable the lot is accessed with heaps of room once the fuse panel is dropped. 30 seconds to change globes if needed in future.
Yes Geoff, I was surprised at the melting as well, plus they were baked solid, and when I touched them , they just turned to black particles. As you rightly say, it's not like the speedo lights themselves, they don't operate much.
No, my pad just sits there, quite odd when you think about it.
The rest of the speedo was all perfect.

the melting is never to do with the heat that the bulbs give out. I think it is to do with cabin temperature cycles when the car is parked in direct sunlight. The heat builds up inside the glass house you call your car and if the conditions are right the speedo acts as a magnifying glass as the sun shines directly at it causing localised heat spots.
Just a theory.

I can see just that happening.
After 43 y arms of Australian sun on and off, your theory could be spot on.
