OK, on the front and rear yokes are you measuring the driveshaft side of the ujoint or the actualy trans yoke/pinion yoke? The most acurate way to measure is to first measure the actual shaft by placing the angle finder on the tube at the 6 o'clock position, thern remove the driveline and measure the output shaft by placing angle finder on the backside of the shaft. For the pinion angle place the angle finder across the yoke where the caps bolt up measuring 12 o'clock to 6 o'clock
