they used the 9 1/4 after the 8 3/4 left sounds like a set of truck gears should be in a 1/2 dodge 3/4 tons at least some 4x4's have dana 70's 60's front and 1 tons dana 80 70 in front. They are not a hodgeciss (spelling?) has a cover on the back, I believe that some car probably had them in the late 70 and 80's / they also used the 8 1/4 at this time
