Audio Steering Wheel Pushbutton Control Lights

Ok, someone please help. 3 out of 4 bulbs under the radio control pushbuttons on the steering wheel are burned out. I have taken the assembly off the the tiny bulbs have a bayonet mount and readily come out. Now heres the kicker. The GM dealers say they don't list the bulbs seperately you have to by the entire assembly for $250+. THIS IS BS!!!!!!! I KNEW THEY WOULD DO THIS TO ME. GM SUCKS!!!!!!!!!!
SO WHAT DO I HAVE TO DO, BUY THE ENTIRE ASSEMBLY, TAKE OUT THE GOOD BULBS AND PUT IN MY OLD ONE AND TAKE THE NEW ASSEMBLY WITH BURNED OUT BULBS BACK AND SAY I DON'T WANT IT AND REFUND ME?

Has anyone had this problem and where can I get bulbs?

Did you try NAPA? What'd they say? I haven't had time to tear apart my steering wheel yet.

NAPA is no use. See my responses under radio lights
