These days everybody wants air conditioning in their rides, and for good reason. Since A/C is standard equipment in almost every new vehicle today, most of us have felt those cool breezes at some point and wondered how we can make our cars rolling refrigerators as well. Not too long ago, most street rods or high-performance vehicles with A/C would have had to undergo a "custom" installation to get cool. It seems that cars that were never designed to have A/C are considered to be the coolest cars on the road, just not so cool on the inside. One of the cars that fits this scenario to a tee is what is arguably one of the coolest rides of all time, the '57 Chevy.

Vintage Air recommends testing the unit before installation. This way if any of the micro switches or triggers have been altered during shipping, they can be easily accessed before installation. It's a simple procedure that will only take a few minutes to accomplish. As you can see in the photo, the triggers for the micro switches could easily be bent or broken.
Yes, a '57 may have had the option of A/C way back when, but it just wasn't that common. Now take that Chevy and squeeze a monster 502ci Rat motor where that small-block (or straight-six) used to reside, and you've created quite a problem when it comes to fitting an aftermarket A/C unit. It's not that it can't be done, it's just that the modifications are going to start piling up real fast.
We set out to find a shop to tackle this type of custom installation. It didn't take long before we heard the name, Buxton Motor Sports of Lake Forest, California. Rex Buxton has been building and designing Pro Stock, Pro Street, Pro...well the list goes on, for years. Buxton has also been in the street rod game for quite some time, turning out hand-built show cars that are as functional as beautiful. Having located a few qualified hands to customize our project's installation, we want to give you a close look at what exactly needed to be changed, modified, or simply moved to cool down this big-block-powered Tri-Five with one of Vintage Air's Sure-Fit climate control systems.

Here is the new control panel being installed in the factory unit. This procedure is done by removing the fan control switch (two screws) and the two screws at each end.
As it comes from Vintage Air, the evaporator unit (under the dash) is plumbed with 90-degree fittings to run the hoses through the heater detail panel. In addition, the condenser and pre-molded hard lines are also designed to be mounted on the passenger side. With the upgraded big-block in place, routing all of the requisite hoses becomes more of a challenge because the compressor has been moved to the driver's side of the motor.
To run the lines under the hood in a conventional manner would be a plumbing nightmare since it would require routing the hoses from the passenger-side mounted evaporator to the compressor, located at the front of the engine on the driver's side. We found that the best answer to this problem is to obtain an evaporator unit intended for a '55 Chevy, which has straight fittings allowing the hoses to be routed toward the driver's side under the dash (instead of going through the OEM heater detail panel then crossing over at the front of the engine). Another part that is crucial in eliminating the routing problem is the bulkhead plate, which connects the hoses coming from the compressor to those under the dash.

So if some particular part is not fitting easily, then it's probably not correct and should not be forced into position. |  All new cables are included...

With the control panel finished, install it before mounting the main unit. This will give you a chance to attach the cables in their proper locations. |
