Since my stock radio seemed to think it was a good time to end it all, I'm looking for a new one.

Looking at this one, or a similar model, but my main question is what I will need to install it. The stock radio is defiantly larger than this one, so I know I'll at least need something to mount it correctly. Anyone else have experience in this and can help me out?
