If you have a working r-12 system just have some r-12 put in it. $50 for new hoses, $99 for compressor.
If you really want to convert to 134 then you may want to replace the hoses anyway. I have heard that the a-6 compressor is not great in the convertion. Look into refitting with a sanden compressor, or any newer model of compressor. Eliminate the POA valve, install orifice tube. Evac and fill with proper oil and r-134a. There is a good thread on this a day or two back that was very informative.
