I believe that any place you can order toyota parts from you just need to order PT413-33310 for the bezels.
You will also need the brackets and the switch.
The bracket for me was part PT297-33002
The switch that goes in the dash is 00550-35976
The main kit is PT297-33000
I got the main kit from Ebay, and the seller of that put me in contact with someone who really helped me with the process.
