photo needed for fire wall a/c hoses location

There doesn't seem to be a standard location for non-factory a/c refrigerant tubes through the firewall. Since most used flexible tubing, the installers could go with what ever worked best for the shop and the tools available.

Don't forget to drill holes in the floor for the knee-knocker drain tubes. Otherwise you're going to get wet rugs and all that go along with it. lol Usually the Thermo King drains are on either side of the transmission hump. The Mark IV units I've run into used a single tube that was usually run though the transmission hump on the passenger side. I haven't run into a Mopar knee knocker unit, though they did make one. The factory a/c cars drained through a single tube in the firewall.
