Hey myles I found a door rubber profile at rare spares in Australia. It has been put on my cab now and is fairly tight, so over time it should wear in. U have to cut and glue for the corners.
Hey ur doing a great job. My TK is at the stage of fitting out the rubber seals on the cab. I have made a lot of enquires in Australia for quarter vent window rubbers. They no longer exist over here apparently. Have you had an luck over there. I included a couple of pics. Regards Ash
