Source for 1969 ABody A/C switch button decals

Backlighting wouldn't show through the vinyl "decal" material that is used on gauge screens, etc...
To install the correct material appliques ( not available ) the chrome sleeves would likely have to come off the buttons. There has to be a blinding edge around that type applique material because light bleeds out its edges. I doubt the chrome would capture that bleed.
At the same time these button stems have yellowed so bad over the years that very little light shines through them anyway. A vinyl decal ( if produced ) would have air trapped in the OEM fonts so it might not lay and stay. Just black and white paint could be improvement. Forfeit the backlighting.
