Looking for replacement plastic interior parts

I've had my 2004 Prius for a couple of weeks now and so far, so good. Today I installed a GTA iPhone kit so I can play my music and podcasts through the stock radio.

The installation requires the removal of 3/4 of the silver plastic panels that house the A/C vents. When I removed the panel that houses the shifter and park button, a large piece at the top snapped right off. I've already run into the issue of brittle plastic in this car with the infamous Gen II upper glove box problem.

Are there places online that I can find reasonably priced, used parts? I called the Toyota dealer, just to get a baseline price, and they wanted $188 for the piece around the shifter. I'll be calling a few of the junk yards in the area, but wanted to see if there were some source online or if other owners had parts to spare.

Thanks!
