A/C Conversion Kit

Anyone know a good place to find a 134a A/C conversion kit for a 1990 GMC Jimmy 4.3 ? Also if anyone has had an experience with doing this conversion, I wouldn't mind getting some feedback.

Autozone has the retrofit kit from R12 to R134a. Just get you the little kit that comes with I think 2 little nozzles. all you have to do is replace the old nozzles with the new ones, and then just let all the old R12 out of your system and use some of that Flush and clean stuff that they sell at autozone too and then refill it with 134.
