I've done it. I used a vac pump for a while then refilled with r134a. Not the best way to convert but it does work okay and has for a few years now. My other fox was converted by the previous owner and i know at least the reciever-drier and the hoses were replaced. It works a lot better than the one I converted. You get what you pay for.
