This post will follow on the floor rebuild and present photos of the tunnel damage and restoration. The tunnel below has already been cut away from the rest of the Austin body, but it’s basically part of the floor that runs along the center of the car. The end you are looking at in the photo directly below would be the view from the front of the car facing the seats. As you can see the tunnel was quite mangled.
Photos of tunnel restoration work
The first step was to cleanly cut away the most badly damaged piece. The second photo below shows a fresh piece of metal that has been fabricated and shaped to the tunnel profile, and welded to the original piece. Then you can see the weld being cleaned up, and finally, the whole tunnel being metal finished. A lot of work for a piece that sits inside the car!
