Found this on ebay, would make a nice addition to my 404.

Anybody know anything about or have this setup? I'm wondering how it performs as well as the mounting configuration.

Of course as the ad says it may not be specifically for a mog.

Certainly not for a 404! Google unimog 404 compressor and I'm sure you'll find pictures of the setup
