Threw away stock head unit when I put in single din now wanna put in double din what
 

So first post here and I've looked for some info and can't find any I have a single din stereo in there now and I want to put my double din in but I had tossed the stock head unit and the cage that I guess is needed for the double din so my question is the cage that was given for single din can that be used for the new double din or what should I do.

The double din metra number is 95-8202 and the single kit is 99-8209

These mounting brackets tend to be the same between double aswell as single din radios.
