90s radio control on steer whl. buttons

I have 2 buttons for the 1990's remote radio control steering wheel option. These came off a late 90s Aurora in the Aurora blue/gray. One is for volume, the other is seek/prog. and are in xlnt. condition. These control buttons usually start chipping and bubbling. I will try to add a pic, if not send me a PM.
