Hi all,
I came across the following sites during my research
for  retrofitting the AC on my Westy Syncro. Some of
these refrigerants require you to be certified to buy
them. In that case go to the imaca site, download the
study manual, study it for 30 minutes, pay 20 bucks
and take the cerification test to become MVAC (Motor
Vehicle Air Conditioning)certified. You can then buy
any type of auto refrigerants. I did this.  However I
took the test at Mainstream Engineering Corp
(www.quick.com)25 questions. I got 24 right-you need
21 right to pass. I guess I should have studied for
the recommended hour.
I can now proudly show off my certificate. You get a
downloaded copy of it right away, then get a laminated
wallet card in the mail afew days later.
Do I feel qualified to to service and repair vehicle
AC systems? No. But I wonder how many "repair" shops
have technicians as qualified as I now am. I CAN
service my own now or just buy refrigerants. Currently
you don't need to be certified to buy R-134a but that
is due to change soon. Anyway here are the sites:

www.autofrost-refrigerants.com
www.lenzdist.com   (they distribut several types)
www.frigc.com
www.imaca.com
www.gti16v.org/tb879503.htm (tech bulletin for
converting VW's including Vanagon to R134a)
www.freezonerb276.com

This is by no means all the sites or types of
alternative refrigerants out there, but it's a start.
I'll probably just do as Phaedra did and use the Wal
Mart conversion kit. It sounds easy.

Bye
