Sorry I goofed on the name of the company. It is FJC,Inc. The book that I have is the forth printing and is p/n 2815 and is titled"A Guide To Retrofitting R12 to r134a". The only other thing that I did that differed from thier instructions was the use of PAG oil and not the esther oil that they recommend. I feel that the manufacturers use PAG as OEM so that is what I use. I have done three 1992 GM vehicles also with excellent results. __________________________________ Do you Yahoo!? The New Yahoo!
