Havent come across either of those, got the Oracal though
There is a GerberFoils.ai on the 2.X cd. It may not be in the "open" and you may have to install it. Insert the CD and select install "extras".
These palettes are not supported by Gerber - these are something I put together a long time ago - so any questions can be direct to me. Here or via email.
