It depends on the faceplate. If you have the one with the radio knobs you probably will. Trace it out with the new radio, then put dome blue masking tape down along the cutting lines you marked out, and I used a Dremel to make the cuts and a small dremel wheel to smooth it. If you have the faceplate with the larger opening then you will need to fabricate some plastic or lexan to cover the openings from the size difference of the radios. You can get that cheap at Home Depot or Lowes. Cut it the same way with a Dremel or something similar. I'm no expert so I've used jigsaws and other stuff to cut it but it all turns out fine.
You can actually go to
http://www.crutchfield.com to check the radio and the fit to your car and what you will need to install it, then compare prices to Ebay and Amazon. Amazon is sometimes cheaper and if you have Prime 2 day shipping is free. I always check all 3 sites for pricing before I order. I've bought more stereo stuff off Amazon than Ebay recently. A Google search will also give you the wiring polarity of the stock harness so you know which is + and - when making connections.
