A65 breather

I am putting an A65 motor back together and I have a few questions.
First...the crankcase breather exits close to the GB sprocket. All I have is a hole in the case. I assume there is a breather pipe to be stuffed into the hole and give me something to attach a hose to....correct? And it is so close to the GB sprocket. How is the pipe retained in the case?
