ridinsmooth,

It is very simple and only costs $15 to take the epa test and get certified so that you can buy R12. I bought some a few months ago for $14.06 per pound. Statistically systems converted to 134 are short lived. I would highly recommend that you simply fix it, whatever it takes and use R12. You can't buy a PF condensor for what the R12 costs.

Your car is not one that is known for the leaky evaporator. Simply flush it and use it unless there is a known leak.

Good luck,
