Couple more updates. Almost have the firewall ready to go in. Worked on getting the wiring pass throughs sorted out and the drivers side piece is now ready to weld to the center portion. Made up some simple carbboard templates to cut out the holes for the Mustang wiring harnesses. Worked great and was very fast. Note sure what I would have done otherwise. Rolled a couple of beads on the part and also step flanged the ends so everything will look flush from underhood after it is welded.
