I gotta tell you I just love these forums because you learn so much. So thanking everyone in this thread for their input.
So as I do the conversion to r134, at the end of the day is there a consensus as to what new R/D part# we should use? and easiest place to get it?
Since i'm a little too environmentally conscious and don't want to just 'release' all the R12 into the atmosphere I have an appointment with a shop in 2 weeks to evac the R12 and do a pressure test to see if there is a leak. Then I can remove the cooler box to change the TXV; also will clean and drain the compressor (unless it's leaking in which case i'll replace it) and refill with PAG, and then of course replace the R/D, and put on the correct valve stems.
thanks again for all the help!!
