Great thread! I am getting ready to make my AC work again and have a couple of questions. (factory air 70 C20)

I will be needing a new compressor and a new dryer. I assume I need to change out the o-rings to R134 compatible. I need to calibrate the POA or have it done. I think I also need to have adapters for the connections, Do I need to replace all the hoses? Anything else? I'm open to suggestions. Of course flushing the entire system will be done.
