<VV> A/C For 69 Corvair

[corvairduval at cox.net]

I'm sorry, but the phrase "no vacuuming of the system is necessary" makes
no sense to me. The vacuuming is to remove the moisture that entered the
system when it was open. This moisture can freeze at the expansion point
(small orifice) and cause the system to not work properly. The moisture
will also allow internal surfaces to corrode if not covered in a layer of
non-hygroscopic oil.

Sound like a really bad idea to me since vacuuming a systemis so easy.

Step 1. Find old refrigerator in alley or dump with good compressor...

Joe:  You found the right place for your question.  I just finished (last
night) 
installing Clark's A/C kit in my 69 Monza.

Feel free to ask me any questions.  It took 9 days and lots of blood 
(literally), sweat (very literally) and some tears but it's finally in and 
working (but not 100% complete).

There is no need to remove the washer mouting, but the tank does slide out
so 
you can get better access for your drill to open the holes.  I also had to 
remove the wiper motor mouting screws (but not actually take the motor out) 
again, for drill access to make the evaporator mounting hole.

The drawing (not the photo) gives you a better perspective of exactly where
Area 
A's holes need to go.

By the way, I found Clark's instructions to be confusing and the pictures
are 
poor.  If you google "classicauto air" on the Internet, you'll see what
clear 
instructions look like.  For the price of the kit, the instructions should
be of 
a much better quality.

I used the 66-67 style condenser in my car since I don't have the skill to
cut 
big openings in the trunk.  So far, the system does work.

Also, I used "EnviroSafe ES12" instead of R134a.  I had used it
successfully in 
my (former) 72 Dart Swinger after my mechanic had to disassemble the A/C 
plumbing.  The ES12a is non-corrosive if it contacts moisture, therefore no 
pull-down or vacuuming of the system is needed before charging.  It's legal
as 
well.

Let me know if you have additional questions on the A/C install...Bill
