I patched an area upper left of the floor seam.
I transfered that bolting strip for the transmission tunnel cover from the old floor to the new floor by trying to hold the new floor patch in place with the tunnel cover on to mark it, (what are the chances the 3 bolts will line up once everything is welded up??)
The floor patch top seam didnt go very well, I cut it a little short and have some gaps. I guess I will have to tack it well and go heavy on the seam sealer
here is a pic of the floor after i put a few tack welds on it.
