You need to replace the reciever dryer or dessicant , flush the system of the mineral oil replace the oriface tube (if aplicable) install the conversion fittings evacuate the system and install the PAG oil and refrigerant.
R134 doen't cool as well as R12 so dont be surprised at the lose of cooling.

No. 134-A is not a drop in replacement for R-12. You will need to recover the entire system and the line must not have traces of the R-12. Plus you need to change out the compressor oil Plus other componants. It will cost you more then it is worth. Check to see if you have any leaks. Leaks are common in the compressor. AC Shops may try to talk you in to getting a retro fit. It is not necessary. R-12 will be a little pricey but is still cheaper then going for the retrofit. R-12 is no longer sold as new in the US. It is now reclaimed which is a “like new” quality. I am sure it will still be around for a while.
I was planning to do the same to my Jeep and my instructor did not find it necessary to go with a change over. I just need to replace my compressor(mine leaked) and then recharge with R-12. also can can't do it yourself anymore. You wil have to take it to a certified tech to do the job. You can choose the upgrade if you want to. It's up to you.

Well I have a newer car, and actually over this weekend I was trying to charge the A/C. On a newer car that takes only R-134, there are warnings that if you use R-12 in it, that it will damage the condenser.
As for the exact opposite, I wouldn't try it. Just stick to what your car takes. The worst that could happen is that your condenser breaks, and other than that... It might take it, but not actually work. So you might end up throwing away a good $30.
Long story short, stick to what your car takes.

Yes. You can take the vehicle to qualified people that will replace the oil and refrigerant in the system and make sure there are no leaks. The EPA has restrictions on this sort of thing. You should not do it yourself. R12 uses refrigerant oil. R134a uses mineral oil. If you try using R134a without changing the oil, you will cause your system to fail and that will cost you more money. You can't mix the two refrigerants or the oils. Once the system is changed over, they will mark it as using R134a and you will be cooling again. It will not cost you as much in the long run if you let trained people change your system over.

R-12 and R-134 are no longer compatable. the two chemicals have diverse particular gravities. The R-12 would desire to be completley drained and the equipment upgraded with diverse orifice sizes in a number of the tubing.

yes,you can.but why change?they sell freon called"freeze12" which takes the place of r-12.but you must be certified to purchase.i think.add no oil, no converison kit needed.reclaim and
e-vac the system to 29.5 of vacumn and holding steady.showing no leaks.make sure you use a set of gauges made for R12 system.use manufactors specs for the amount
