Pinion angle and driveshaft length.

Example. Say with the SS leaf springs i want to be 5* down. Street car with limited strip action. If i were say 2* down on the trans tailshaft. I want to be 7* down on the rear pinion pinion correct?[/B]

Try again... :(

Trans is 2 down, where does the pinion need to be for a 0 angle?
