These were not. I believe the gear ratio in the rear axle was a big discriminator but I'll need to research that in the parts manual. I suspect there are two ratios one near 0.97 the other near 1.3 but these are a guess. I'll try to firm up the knowledge and repost. There are gear drives in the transmission that come into play as well and I suspect it's because of these that there are only two ratio adapters.
EDIT: this chart from the parts manual lists two adapters for a 3.73 rear end and several for 3.07. The chart is for four speed manual transmission equipped trucks. There are other charts for auto and three speed manual.
