A/C refrigerants ... r-12 to r-134a or HC

[MXHOWES at aol.com]

I would like to get some CONSUMER input about retrofit successes or failures
using alternative refrigerants to r-12. In searching the web it is very
confusing because most of the information comes from someone who has a product to
sell, ie. enviro-safe, freeze 12 etc. or the A/C shop owner who (like the Audi
dealer) wants you to believe that THEY are the only persons qualified to work
on your system.

Let's assume:

1.  You are going to vent your old system the proper way (this subject has
been covered well)
2.  If you post to this topic, you are a consumer with first hand experience
in retrofitting your own car or having it done for
     you.

If you have done a conversion please state what components were replaced.

Thanks, Jim
