Here are 2 drawings. In each the engine/trans assembly is lower than the rear and is in the car with the tailshaft 3 degrees down. In the top one the pinion angle is 6 degrees positive and the centerlines are parallel. In the bottom one it is 3 degrees negative and the centerlines are not parallel. Which way would you set up your car?

If the results don't match the theory, change the theory.
