Mopar Muscle Association UK

Does anyone know of any UK based company that can refill an American air con system with R134?
I understand that it can be done, but Google is giving me nothing of any substance.
I want My Grand National a lot colder than it currently is, if possible!

Hi, this company is great... They can do almost anything with classic aircon. Ask to speak to Steve Henshaw, tell him Steve in Neville Road with the Cream Polara reccommended him and he should see you ok. Very nice guy, lives local to me and is very knowledgeable.
