Pics of cab

[Winchester]

My tractor has a semi closed cab. As a summer project I would like to make it all closed with door and everything.
But I see a little problem around the steering and steering arm.
Anyone got some pics of their dexta with a cab on for inspiration and maybe how they have solved it around the steering arms?

Have a google on Dexta cab images, there's a few out there. Folk seem to have a bit of rubber or canvas across the steering arm area, maybe with a hole for the rods to pass through.
