I installed the gear set in my project 1965 Ford Falcon sedan delivery that I converted to an all electric vehicle. The 3.8:1 ratio gear set works fine for my application. I simply set up the correct backlash and the gears are perfectly quiet. A word of note to anyone that performs rear end work. Synthetic gear lube is the only way to go!
