You can still use R12 as long as you get it filled at a certified A/C service center. If you want to convert to R134a, you still need to go to a certified A/C service center for proper installation; one of the things that needs to be done is total evacution of R12.
I just did the R134a conversion to my car...And supper supper easy and Great cold air once again......Cost 25 Bones for the Kit (Had the filler hoses With gauge 3 cans of 134a with sealer and conditioner and the fittings) and 20 for the evacuation of the R12 and well worth it...The System on my 89 works fine the hoopla about the seals not working was done in an effort to prevent people from evacuating their own systems to do the conversion on their own. Most AC shops will evacuate your AC for about 20 dollars in Texas austin area. Tell them you are removing the system and want it evacuated before you remove it. Then just take it back to the house and use a seal conditioner and filler combo and it all goes well

i heard there's a type of auto refrigerant that is a compatible replacement for R12, but i don't know the name of it. some dude at an Auto Zone told me about it but he didn't know the name of it either. apparently its not sold in many places. all i need is a name so i can search for it. any help guys?
Now that i have the freon, how do i replace it? the instructions say that i need to remove the remaining freon before adding the fresh stuff. But I'm about 90% sure there is no more freon. Do I really have to get a vacuum and pressure gauges to monitor my high and low pressure and remove the remaining old freon? Can I just fill in the new stuff and not worry about it?
