Thanks for the great replies. I didn't do the conversion. It was done by the previous owner in March of 2004 (about a year before I bough the car). The record shows he bought a $34 R134A conversion kit. This doesn't sound like he replaced any major parts, does it? How extensive is a "kit"? I think I should probably change the tubes and major components that I am able to, then bring it to the shop for final tweaking and refilling. Is that reasonable, or are there other items to be aware of when replacing components?
