C15 no 12 cab: oil filter mounting?

[odwillys]

Hi All
Back again, can anyone give details on where and how the oil filter is mounted?
The plumbing is simple but for the life of me I cant work out where and to what it is mounted as unfortunately I purchased the vehicle as a rolling chassis and a large pile of bits and pieces so its a bit like a giant jigsaw puzzle.
Thanks In anticipation of a member having the detail.
