R-12 costs my dad wholesale about 30 bucks a pound...our cars need 3 pounds..
if you want to bleed the system just unscrew a line and let it leak out.. be sure to hold back on the oppsite side of the line (use a wrench for each side) because everything is aluminum and breaks easy..
its cheaper to top off an R12 system then it is to convert it to 134a but only if the system does not leak...
the a/c lines in my car were shot so i got new ones with all the orings i needed, a new evapotator (silver canister) and an oriface(like a inline filter)...the parts total was about 100 bucks..plus 90 for the lines(extremly hard to find for my car)..i drained most of the compressor oil and re filled it to spec.. it works beautifully...better then it did with the R-12
