Well, finally both side floor boards are in and tacked. There was quite a bit of fitting and massaging but they are where they need to be.
I originally wanted to use the original tunnel but since this car has a 9" rear end with an offset pinion, that wasn't going to work out too well. Plus, the more I poked and prodded, the more questionable metal I found. So out it came....
Though you can't really tell in this photo, the rear of the tunnel is 2-1/2" wider than the front and is shifted toward the passenger side. This allows for plenty of clearance for the drive shaft.
