Chris, I have converted 3 of my personal cars over to R134A and have had no trouble. Just have to have the right person to charge up the system. But, Due to the cost of R12 and less people handling and working on it, I would go to R134A. All the parts are readily available and plenty of people to work on it and R134A is still cheap. We have new compressors already with R134A oil loaded in them.
