Pinion angle question.

Try think of it this way. Ur trans is at 0*. Pinion needs to go down 2.5-3* from zero. So u need to be 2.5-3 negative angle. So then no matter what ur trans angle is u have to be down that much more with the pinion. Even though the pinion angle may be -5.5* u r still only 2.5-3 down from the trans. Kim
