Correct way to set rear angle?

Treblig, Thats the exact article I used to set up my thought pattern. It shows that the rear must run parallel to the transmission output shaft which is just an extended line from the center of the crankshaft. Using the balancer as a 90* reference and the face of the rear housing on a 90* reference I am thinking that I had the parallel lines. Then by dropping the rear down 6-8* should give me the 6-8* drop? I am asking if my thought pattern is correct. I just dont want to weld and find out I miss understood. So are you saying yes its good?
