I found a yard near me that has 12 Corolla's and 8 Prizm's
Look at www.car-parts.com
and you can find all the yards near you.
Some may not let you remove the parts yourself but if you tell them what you need or have a list they may just tell you to go grab them.
You might have to call ahead and see what they have and tell them what you want so you can get a feel if they will let you getb your own parts.
