Radio buttons wanted.

Taking the radio/casstte/cd out of my discovery 1 the other day, I broke two of the buttons Loctite's finest couldn't fix them and I can't find any for sale on the internet/ebay. Does anyone have a couple of buttons off an old broken or disused unit they can send, please? It's the phillips unit and the two buttons that broke are the forward and back buttons that you skip cd tracks with. Also needed to reset the code after disconnecting the battery!

Thanks
Steve
