When you convert R12 to R134a you need to have your compressor rebuilt, replace the hi and low pressure hoses, put in a new orifice tube, and replace the receiver/drier. The condensor and evaporator don't need to be replaced. However, on an older system (ie. one on a classic car) I think it would be a good idea to have the system flushed to make sure you don't have any crud in the condensor or evaporator.

I converted the AC on my 1990 Buick Estate Wagon as I described above and it worked like a champ. It didn't blow as cold as the factory manual said but it was might CHILLY during the middle of summer. For AC parts you should try Kanter or Fusick.
