My thinking through the years has been to leave a degree or two between the two, so that as power is applied to the tires, the pinion will rise a little and the two angles will be very close together. Like, if the trans shaft is 3 degrees down bubble, I might put the pinion in at 1 degree up bubble. Like I said, under power, the pinion will climb the ring gear and the two should be pretty close to equal.
