One or two years of Grands have oddball gears, the rest are the same as TJ low pinion gears. The lockers are interchangable from all Dana 30s from the early 70s to current.
The axle shafts are basically the same, some grands with the x over knuckle on the pass side had unit bearing spacers. 1/4 spacer between the knuckle and the back of the unit bearing.
