Thule Vent Shaft replacement

The Thule Omnivent Shaft isn't long enough for our van. The replacement only sends the metal shaft, so this replaces the container if you cut the existing one off.

2 versions made, one with a base, one without (to glue).
One is up the other way, so there is less need for supports.

I do not believe you need to glue the metal shaft in, as gravity will hold it in place.

Both shafts contain a cut-in for the rubber gasket to go.

I have yet to fit this, so it may change.
