1. Place the ARB differential Cover on a bench next to the standard differential cover that you have removed from the vehicle.

2. Using a straight edge (electrical tape does a great job), make a line from the bottom of the standard cover's filler hole to the corresponding point on the ARB differential cover.

3. Hold the Dipstick/Filler Cap on the outside of the ARB differential cover so that is is sitting in the position it would be if it was just placed in the filler hole. From this you can determine how far up the dipstick the oil level should be.
