Peter the receiver/dryer is the only componet you need to replace. I did my 308 a few years ago with 134A when I replaced my compressor. Easy conversion just need to vacuum down and fill it up with 80% volumn of 134 |

I converted my 86 Testarossa a couple of months ago. I drained the compressor and refilled it with a compatible oil, replaced the dryer and pressure cut off switch and then pulled a vacuum and charged it with 134a. Works great! I had a local AC parts place match up the dryer with a compatible pressure switch. The parts ran me about $90.00 |

Peter: I've heard about incompatibility with some rubber and other parts with R134a. Like seals, possibly O-rings. Mostly affects older cars. |

Don't think you can get all the old oil out of the receiver/dryer. In that case you would be mixing oils. |

I'm told the only thing that needs to be done to effect a conversion from old to new refrigerants is that the old oil must be drained and replaced by a compatible oil, system evacuated and modern refrigerant put in.
No seals or any other hardware needs to be replaced. True/false?
