Ahhh... where to begin. Plans shifted a little, but making some slow progress...
Going up on the Fab Table:

Perimeter rail installation begun:

Floors marked:
3" section removed in order to insert the rail, but keep the car sqaure until it is tack welded down to the table:
Next, clean up the actual area where the perimeter rail will be welded to the car, tack weld to the table at ride height, and remove the rest of the floor...
We'll see how much time I get in the next few days/weeks..
