David... If your system has no leaks you should be ok but because 134A runs at higher pressure you have to put about 13% less refrigerant in it. If you had small leaks they will become big ones pretty soon. I had my OLDS converted, they could not find the leak so I decided to make the change since the 134A was cheaper...big mistake, it found all the leaks, where before a charge would last 2 months it was now 2-3 weeks. I ended up having to replace the majority of the system, big $$$$, It does work great now. On the SAAB I had to replace the double hose and stayed with R12.
