Fill it to the original Ford level with a good quality oil and it's good.

Idk if it was me, i'd buy some gear lube and fill until it was at the bottom of the fill hole. If i came up short i'd buy more if i bought too much i'd put the left overs on the shelf so i'd have it on hand.

If you donot have the rear end modified to keep all the oil in the center during hard cornering, then overfill it at a minimum of 1/2 quart. We modify all of our housings to keep the oil in the center.
