i have read many threads on A/C systems and they are all about cars already fitted with compressors. for those now without A/C, and just possibly with black mb-tex, what's the best approach?

i myself live in a marginal region, so i wouldn't need a large compressor, and i don't care about making a bracket or the choice of refrigerant. having removed defunct A/C from my old car, i have the impression that the hardest part of the job would be mounting the condensor and hoses.
