A/C repair & restoration options

My A/C is now fixed and once again ice cold, and not a minute too soon with the 100*F temps today! Anyway, it would appear that one of the O-rings on the receiver/dryer literally disintegrated itself over the past 22 years; the ring that came out looked more like a rubber skid mark than an O-ring. Put on a new receiver/dryer, and had the shop evacuate the system for about 45 minutes on a deep vacuum. Then I had them check to verify that it could hold vacuum for at least 30 minutes after shutting off the vacuum pump. It did, so I had it charged to spec with R12 and had them add in some UV leak detect dye just incase. With the temps today at about 100*F, my vents were blowing out air at 47~50*F once it was fully charged, not too shabby.
