The firewall is a good thick piece, so I went high on the welding amperage to make sure those cracks were fully penetrated. Then I dialed it back and filled the drill divits. We’ll be plug-welding the new bracket on – it’s the only way. This is spot-welded to the firewall panel off the car, then the bulkhead is assembled. Now, there’s a bracket welded in directly behind it and there is no chance of getting the tongs in there. So plug-welding is the only answer at this point. So – I welded up all the divits so that I can be sure to grab good thick metal for each plug.
