A perfect rear angle will be parallel to the trans angle. So theoretically you'll have to move the pinion down 12 degrees. A 2 piece driveshaft helps with these angles as you can fudge them a little more. I would start with a 6 or 8 degree shim on the rear diff. Or if you can push the trans up? (not usually)
