Itinerant Air-Cooled

There is seepage coming from the side of the transmission behind the CV in the area Bentley calls the "final drive side cover". I've studied the drawings and procedures, but they've combined so many different jobs I'm not sure what to do.
It must be a leaking oil seal, but which one? Is this a driveway job? If anyone has advice I'd appreciate it.

Scott posted a detailed procedure for this in a link on the samba.com

Thanks I'll try to find it.
