I have no disagreement with what you have posted, but also note those models are their civilian truck models. My Chevrolet G506 1-1/2 ton came with 6.67 gears which were sometime in its life replaced with 6.17 gears. The tape label on the box also noted 1940-6 GM & Studebaker ARMY. I added the emphasis as it seems important. I have also attached a couple of new photos to answer quesions regarding tooth count and also inside diameter. They are ring gear (40 teeth), pinion gear (6 teeth), gear ratio 40:6 or 6.67:1. The inside diameter is approximately 7-1/4"
