A body 8.75 dimensions needed

Crackedback

How about mounting face at 0 degrees straight up and down instead of being angled up 2 to 3 degrees? II believe mine is set this way right now. What do you think?Is mine angled too far down? Driveline issues or am i getting too crazy about this? Reason being is that while its just an empty axle tube and i can easily carry it around i would like to make sure its set up with the right angle. I would hate to put this in the car figure out theres a prob with pinion angle later, and have to remove the axle, cut off and reposition the perches. If i need to move them., cutting them and moving them now would be easier.
