I am not talking medium duty. This is for the 60 61 and 62 half ton 4 wheel drive trucks. After '62, you are certainly entitled to your opinions and facts, but pre '62, and NOT Napco, the 1/2 tons were the ratios specified above, namely, 3.90 and 3.92. rear and front respectively. I guess I'm going to have to send you a copy of the manual's page , cuz so far, you're not believing me.
