Reviving a 44yo ac system tips ???

Yes I completely dismantled the compressor and clean and put in a whole new gasket set including the shaft seal, torqued all the bolts. I'll use your advice as a guide so thanks you for that. The dryer will stay sealed till it goes on. Once I get it all together I'll take it to my mechanic for vac and fill, I'll make sure he follows your directions. I did find the vac hoses coming through the firewall are dryrotted so I'll replace those all the way to the switch. Is there a kit with all the proper size orings?
