Looks like that one has a more up to date steering column as well. I cannot help with the supplier of that material but here is a photo of my Traveller dashboard.. I made it from plain aluminium sheet and then lacquered it.
I added a cigarette lighter socket in the top left corner to use if we need the sat nav on long journeys, that digital unit shown in the photo is a cheapo volt meter and internal temperature gauge that also has a USB socket. Last Wednesday (the day before the heat wave it was showing 36° C inside the car with the windows open. So I decided to use my modern air conditioned car on Thursday when it got really hot.
One good thing about the hot weather, I think I have now proved that my fuel pipe lagging and carburettor heat shield are working. The car ran perfectly with no signs of vapour locking.
Purely for interest this is the dashboard I made for my Austin 7 Special many years ago, I engine turned the surface with an emery disc.
