JD many thanks the previous owner put a newer rear axle on it with disc brakes but at least I know what oil to put in it and roughly how much

Various rear axle types and oil capacities (ranges from 6.3 to 22.0 L). Likely that if it's an 0811 it will be 6.3 L but to be sure you would need to state the details from the vehicle identification plate (on passenger side door pillar) - it will give a 2-letter code under "Rear Axle Type". For the lighter Ford axles, the correct oil is SAE 90 EP.
