Need spring for idle set screw

[1Rocketman]

Recently I added an angle boss and replaced the IAC, TPS and some other minor underhood work. In the process of resetting the TPS, idle, etc, it looks like the spring that wraps around the idle set screw has disintegrated in several places and is floating freely. I noticed it tonight when I was checking something else. Any idea where I can get a replacement without having to get the whole assembly?

Thanks in advance.
