You should be good to go then. Just put an angle finder on the drive shaft and a perpandicular or parallel part on the center section. I put a bottle jack under the pinion snout of the diff and crank 'er up until the readings are within 3 degrees, then adjust the uppers for length and install.
There should be a couple of flats on the rear of the centersection of the axle housing, to either side of the diff cover (where the axle tubes fit in). Those are 90 degrees to the pinion angle.
