Does anyone know if the needles can be changes on Sierra and cossie speedo,rev counter,fuel level and coolant level?

The reason im asking is cause ive noticed the orange paint(or what ever it is) has come off my needles.

I was thinking about getting a set of clocks and swapping them over.

Ive had a look today,the speedo needle looks to be tight. The black part of the needle comes off but i couldnt get the rest of it to come off.

Any help would be grateful.... thanks.
