You know Peter, I couldn't remember from whence it had come when I did the evap in my 124. So I just left it out; hasn't blown up yet. I stared at that sucker for a long time, it wasn't even apparent what the purpose was.

Here's a guess. It protects the fragile evap from shrapnel thrown by the fan?!? So place it between the evap and the squirrel cage.

Other theories on its use and purpose welcome!
