3/4 ton 2WD is 30 spline.
Also the differential can be changed out for 2WD as long as it is the same axle housing, because 3/4 tone stuff is hard to come by. Just make sure the studs are in the same spot, and you can drop a 2WD diff in the 4WD housing, and run those axles too. Also make sure it is from the same year range or your axles will be different lengths.
