This law is probably broken more often than the speed limit, but it is the law.

I read the law differently. Those are rulings (which carry the force of law) are the SNAP rules, which restrict replacement of ozone-depleting refrigerants.
If you are converting FROM 134a, you do not need to change fittings. At least, that's my reading of it. It's pretty much impossible to change the fittings on a factory-134a system, and I don't see anything about converting a converted system, as long as the original 134a conversion is not a "sham" conversion.
I'm not a lawyer and certainly not a judge though.
