Stevebfl,

On "shortened life", you mean the compressor?

Since this is an '89, would the "stock" switch on it be the right one? I.e. if the switch was never changed, would I have the right switch installed?

I hear all these different things about the pros and cons of converting. It's like the oil thread here - I did a lot of reading, and it seems that there are various opinions on it. I for one like the fact that with R134a I can actually work on the system myself. Bought the gauges, did the expansion valve myself, vacuumed the system, and filled her up. You need a license to do that with R12, not to mention the environmental issues (my fiancee is an attorney at EPA). But I am also aware that the system will not be as efficient as R12.

Thanks for responding.
