I was looking at Camaro restoration pictures, comparing them to my own car, and I noticed something about all the other cars firewalls. On the passenger side where the heater goes, there is a much larger hole, than on my car. Im not sure if this is just for cars that hard air conditioning, or what. On my car, the hole was welded shut, but we removed the plate that was put there. And where the exstension to the hole, should be is just solid metal. Here is what the firewall looks like http://images.cardomain.com/installs...15_26_full.jpg
Will a heater work still even with this hole? And if not, can someone point me in the right direction, so I can correct this problem.. Thx!
