96 Prizm Inside Dash problems

My stereo on my 96 Prizm got boosted a few months back. The CD player was attached to the cup holder and they ripped it out along with the CD player. I've found the discontinued part, but now I've found out that I'm missing certain parts on the inside that secure the cup holder. I've no idea what parts I need and no idea where to get them.

Can anyone tell me where to find these parts or give my any advise/help?
