Dan,
Any A/C compressor repair shop can make hoses for you. I had mine made for about $100. By routing over the fan guard
look at this setup. A simple R134 conversion kit at the parts store has the O-rings and oil you need. I believe they are green o-rings. The orfice tube is over the counter parts too. The accumulator cost anywhere from $40-$100 according to
www.carparts.com. I would definately replace the accumulator since any shavings or dirt collects at this point. Once the system is rebuilt, a professional should pull vacuum on it for at least 15 minutes to check for leaks. Once it passes charge it up with R134.
