Since you went through all that why did you not change it BACK to R12? If you had, there would be no need for a PF condensor. It might be easier and cheaper to just change back to R12. R12 can be had for $14 a pound now. I just bought a jug of it for that. 134 is going up in price rapidly. This offers a very simple and economical fix for you.

If you still want to try a PF condensor, go to www.ackits.com. Get the phone number and call those guys and talk to them. They are very helpful and KNOW their stuff. They sell lots of PF condensors. Ask them about whether they recommend 134 or 12 for your car.

Good luck,
