Default 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....

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.

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.
