Does anyone have a good picture of a firewall with the holes for the heating hoses? There are several more holes in my firewall from an aftermarket AC unit and I am not sure which ones to have the body shop weld closed. An original firewall with just the heating hose holes would be great. Thanks.

Carl, the holes that are closer to the center are for the heater hoses. My 240z had what yours has now.

Here is a look at my 73 that never had air.
