The floor half sections usually don't include the center part. They're made to just replace up to where the tunnel welds onto the floor. If you buy a complete floor, it includes all of it, but I don't think you can get a complete Bugeye floor, just the later floor with the access hole for the front universal joint. I got my floors from frogeyespares.co.uk and they were the same as Moss, but I knew it first. And they only cost $107.70 each. Take a look at the rebuild picts and you can see how I assembled mine.
