How much oil to use

Year: 1971
Make: Ford
Model: Thunderbird
Engine Size: 429
Refrigerant Type: 134
Country of Origin: United States

I'm in the process of repairing and converting the AC on my 71 T-Bird to 134. I've already replaced the compressor, new York style, - old one was leaking - receiver dryer, expansion valve and the condenser core - fittings disintegrated when I took the hoses off the old one. I'm planning to use ester oil and have my partner's mechanic son pull a deep vacuum and charge it with 134. I need to know how much and is just pouring the liquid into the compressor the way to go or is the stuff that is pressurized in a can with some r134 better?

Forgot to mention above, I did go through the entire system and replaced the original black o-rings with new green ones.

The oil goes in the sump on a York compressor. The manual for that compressor describes checking the oil level, and oil charge in detail.
