Phasing drive line?

I don't know if that is the correct wording. Trying to set pinion angle on my 72 Swinger. Has 440, setting on an Altercation, 727, new balanced Al driveshaft, 8 3/4". I noticed, while I had the car in the air, that the tranny, looked like it was pointing a bit to the drivers side, in comparison to rear yoke. So I dropped the drive shaft and attached a laser to the output shaft. I was correct. It was a degree or two off.
Suggestions on correcting this? I know I should address...
