Rally wheel paintcode????

[72C3]

Does anyone know the paintcode for a rally wheel .  Had a look at mine the other day and it looks like the original wheel and tyre.  The spare wheel from my 72 and is a bit rusted and needs some work.  Stripping repainting will be required.  Obviously the tyre is a write off but I will keep it for prosperity. Any experts in this field that you know.

Dunno the GM paint code but the colour is "Argent Silver".
