It it were me, unless restoring to factory specs, I'd replace everything with a modern set up and pull a vacuum and be done with it. R134a just does not cool nearly as well as the original R12 Freon. R134a will not only leak from the 0-rings if not replaced, but can even leak through intact hose OE walls because R134a molecular structure is smaller than Freon.
