Any Australian wrecker since they are a standard part. Also Australian Honda/Prelude/Car sites (preludeaustralia, ozhonda, boostcruising) where sometimes there is a car being parted or JDM halfcuts, etc. Seen those turning lights pop up before too and with the AUD being so low there could be some good deals, although things like JDM half red dash's wouldn't really work.
A good place to start would be to put a request on:
Parts Locator - the no1 autoparts directory
AutoParts.com.au - Reach over 500 Wrecking Yards with one Request
They all ship interstate and accept CC payments so I can't see that shipping to the US would be too much of an issue. I have seen the panels going for ~$40 each so like I said around US$50.
