What to do with a missing radio?

[spdfrek]

I searched and couldn't find anything, but what have you guys done with the stock radio holes in the dash? I was thinking about trying to find an old radio to put in just so it looks good but I don't know how hard it will be to find something like that. My other idea was to cut metal and just weld it all shut, but I think that will look stupid. What did you guys do with this area of the dash? I need some ideas.
