Like Frank said, Industrial Products Company was John Zentmeyer's company. The gears will fit any of the 9-5/8" differentials you find in the later Dodge 3/4 ton (and 1-1/2 ton) WCs, all M37s, and all Power Wagons and M601s. I never knew that John made 4.89 gears, but I'm not surprised. John was one of the pioneers in making new parts available for our old Power Wagons, and was a top notch researcher and historian.
