When I started thinking about the crawl through, it was a bit daunting, I have looked at other trucks and seen various methods of making the seal.
I knew that I didn't want to have to do anything before lifting the cab, like undo clips or bolts or anything like that. I would simply forget and would end up breaking somthing.
It ended up being a lot simpler than I thought it would be.
I started by making the tunnel out of 3mm steel, this will be fitted into the front of the body, the face of that tunnel has a seal on it that mates with the flange I made to fit into the hole I cut in the cab.
As the Tatra's cab is live mounted to the chassis and not rubber-mounted, it doesn't move, so the seal mates perfectly
Here are a few more pictures.
