Here are some pictures of the modifications you'll need to do on the stock radio face plate (and even the Metra Double Din faceplate as well)
Everything circled in red will need to be removed as they interfere with the fit and the face plate sitting flush with the front of the stock radio curvature
In the last two pictures, I'd recommend completely removing those sections as a precaution.
Also, credit to "Ron" for the first picture. I had already cut up mine and stupidly forgot to take a picture of the before and after with the tabs removed. Luckily a google search showed me the pictures I needed and i cropped out what I didn't need from his picture.
