Re: Restoring old air conditioning
No problem legal wise with the current compressor. Either R12 or R134 works fine. If the hoses are original, the large ones are probably end of life. I would replace them as part of the process. Especially if going back with R12. Would suck to have $100 worth of coolant leak out of old hoses.
I have had the clutch replaced on the old style compressor without the mechanic needing to break the refrigerant seals.
While replacing hoses, might as well replace the filter/orifice tube.
Most folks recommend replacing the dryer as well but I skipped that when I replaced the compressor 15+ years ago and it is still working fine today. But the system wasn't dead very long before I did the repair. I also stayed with R12 as I had some purchased before the ban happened.
If swapping to R134, the general recommendation is you flush out all the old R12 oil before adding back the oil for the R134 coolant. Apparently, the two oils don't play well together.
