Under Dash A/C
68 GTO
Getting ready to pull the trigger for a Mark IV under dash A/C unit from Vintage Air. While I have the engine, dash and seats out, I thought it would be the best time to install the components. Anyone else running an under dash A/C? Any interference with the manual floor shift? Best routing of the refrigerant hoses? Photos of the hose routing and interior? Trying to maintain a period correct appearance so not interested in the integrated system.

I used classic auto air in my 69. I had the interior all out. It went in easy and works very well.

Where did you cut the firewall holes for the refrigerant lines?

I have the vintage air kit in my '65.
The lines are run where the stock evaporator would go...behind the passenger side fender. I am also using the OEM control panel conversion kit. Works like a champ.... Jeff |

In my kit the refrigerant lines go through the supplied firewall block off plate.
I thought that vintage air routed them through the kick panel opening. Sent from my iPad using Tapatalk Pro |

If you want to be period correct, get a large grommet and drill a 2 1/2” hole below the heater plenum. This is for the high and low side hoses and the compressor lead.
Then drill a 3/4” hole in the lower part of the firewall for the condensation drain hose. |

The instruction manual for the Mark IV is here: https://www.vintageair.com/instructi...672001-VHY.pdf It doesn't have specific information for particular vehicles, but is still worth looking through in advance before buying.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
