Glad to help. It's just a big puzzle and has to be pieced together in the right order.
I did mine long enough ago I can't recall what the angle was. I basically took my old rear end, set the axle pads to be level (with a angle finder) one once they were level, I checked the pinion angle. Then when I setup the new rear end, I just got the pad at zero and set the pinion to the same as I measured. Cake!
