When building race car point the pinion at the trans tail shaft then adjust the finish angle of the pinion to the driveshaft for the type of suspension used.

This is pretty much how I do it but I set the engine/trans
in the car and set the angle of the engine so it points
in a straight line(I use a laser in the rear main
and line it up on the pinion so its all in line).. then
when done roll the pinion to what is needed(1 or 2
degrees)
