Steering box oil level

[Steve Rinaldo]

I just finished replacing the light switch on my 31 A and I tried to get as much of the old oil out as I could. I know that it should take 4.5 oz. to fill the box and in trying to refill it I could only about 2 oz. in until the kevel of the fluid was at the top of the fill hole.
1. Is there still lube left in the box after a light switch replacement?
2. when the steering box is full where should the kevel be.
Thanks, Steve
