Tom is correct the Service Bulletins detail each step, however it is my experience you will never get it properly adjusted in the car. Bite the bullet and remove it from the car so you can work on it on the bench. Also unless you have a low mileage car you should replace bearings, cups, worm and sector. After 80 years of driving and in most case lack of lubrication all these parts are worn. I have spent hours trying to adjust the gear after only replacing some of these parts but if you replace all the parts adjusting is a piece of cake. It take longer to read the Service Bulletins instructions than to do the adjustment. Also don't forget to check the steering balls, if they are more than 0.015" out of round replace them. Then check the axle for straightness, 90% of the axles are bent. All these pieces contribute to ease of steering. Rebuild the entire front end and it will steer like a dream, no need to buy an expensive later model steering box. Rebuild the original and you will be amazed how easy the car steers. Just my thoughts.
