Read with interest the input. Query- Why make it difficult when its so
simple. KMart sells a kit for $39.95 which includes the new oil, 3 cans
of R134, Filling hose and all the fittings necessary. The only thing I
added was a can of AC stop leak. The system had a very slow leak and
emptied itself over a period of 6 months or so.   R12 & R134 are
completely compatible. No other parts need be changed.

The conversion was done almost a year ago and is still going strong - -
no problems- I use it here in Fl. most every day.
