During Mark's visit we decided we'll replace the left inner firewall too. Bottom edge is pretty rotten. Another one of the time vs. dollars decisions. So away I went cutting out the firewall.
Started with unhooking the left heater tube. Start by cutting and removed the e-brake tubes from the engine side. But first one must get rid of the seam sealer.

Just assholes and elbows.

Angle of the drill. If not perfectly square you snap off the teeth. $7-$9 , cha ching. To speed things up I cut out the left inner firewall right with it.
I am going to like removing the inner firewall to tunnel welds from the inside much better. Pretty messy from the outside. From the outside you have the cutter on the portion that you keep. Big holes.
Preferred method is cutter portion on the portion that is going into the recycling can.
