I know the argument back & forth over the different types of refrigerants... What I want to know is if anyone in the group has replaced all of the needed parts themselves? (These parts would include the compressor, acumulator/dryer, evaporator, and oriface tube.) If anyone has replaced these parts, where did you get the parts, what are the part numbers, and how much were the parts. I have considered going to a local conversion shop, but I worry about them doing a "complete" job. Last question: has anyone had good or bad luck with a conversion shop? Thanks in advance for the information... If you wish, you may contact me directly at tahoe98@xxxx Ben Boatright VIN 10115
