Thanks Richard I'll try your source but before doing so and whilst searching the internet I came across these two photos of what appears to be images of transfer case but the vent differs, is there any reasoning behind this?
I then went on to look at my butchered vent which might suggest it was squashed to enable it to be fitted below the chassis cross member.
Any experts out there that might shed light. I'm thinking I may have the wrong vent.
Cheers,
Paul
