If you don't replace the drier and exp valve, you are being "penny wise & pound foolish". If the system has been opened for just a couple of days, the drier is shot, already. You said the system has been open for about 10 years, so the chances are excelent the exp valve will be stuck. Changing both of these parts at the getgo will be cheaper then the R-12 you waste, when you have to open the system, again.

I already have a new drier and expansion valve. Since I moved, all of my stuff is packed away somewhere that I can't find anything, so I'll be going with R134a. There's a place not far from me that builds custom hoses for machinery and I'm going to stop in to see if they can rebuild the a/c hoses on this. They're still very flexible and don't make any kind of noise that you would expect from old rotted hoses, but I don't think they'll hold for very long. There were already 134 fittings on it so it had run the stuff before, so I expect it to work. I'm gonna flush the lines and condenser, but I just don't know the condition of the evaporator.
