<VV> Clark's A/C Instruction booklet

I installed a 66 factory system in my 65.  I used the Clark's repro of the 
GM manual and the Clark's templates.  Can't verify if 69 models have all the 
dimples in the body, but the 65 and 66 models come from the factory with 
locating dimples for add-on factory A/C systems.

Examine the area just below your windshield wiper motor.  If 69s have them, 
you should find dimples for two of the evaporator bolts and the cutout for 
the liquid line to the evaporator.  To the right of the passenger windshield 
squirter there should be dimples to locate the factory fresh air cutout. 
The blower housing requires one big cutout, not two.

I believe there was also a dimple to locate the large hole on the passenger 
side just below the rear seat cushion where the evaporator suction line goes 
from inside the car to underneath.  I also mounted a modern parallel flow 
condenser in the trunk with a large fan in the bottom of the trunk.

If you are installing a factory system and you intend to use R-134A 
refrigerant, you may want to convert all the connections to modern O-ring 
All modern cars for quite few years have used O-ring connections.  R-134A 
really doesn't like Corvair style hose barbs and hose clamps.

Those that have installed a factory A/C chime in here.

A Corvair without A/C in a Las Vegas summer is a Corvair from Hell!
