Where to mount an oil catch tank?

Hi people, where do people mount their oil catch tanks in their 172 bay? Thinking of getting one but can't visualise where it would
go!

Pics would be helpful

I'm wondering this as well..
Iv got one coming in the post.. gonna try to make a bracket that mounts to the same place as the header tank.. theres a bit of room at the back there
