With the left and right floor pan complete then next was the trans tunnel. The truck will have a 700R4 trans and I wanted plenty of room for it to fit.. especially since I didn't have anything rigged to mock it up at this stage. I also built a cover plate for the battery access panel and welded it into place. I will use a drop down battery box instead.
The first thing I did was fab a flat panel base to fit within the stock floor recess with a step around the edge. Next I fabbed the lower portion of the tunnel with the english wheel and welded it to the base.
Then I temp attached the tunnel onto the floorpan with clekos and used painters tape to pattern the upper portion of the tunnel to fit with the firewall. Once I plug welded the tunnel to the floor, I then fabbed the upper portion and welded it into place which left a few areas in the corner. So I made some tape patterns of those areas and closed them out as well.
