Building A Better Bow Tie, Part II: Rear Suspension - The Stovebolt Saga Photo Gallery
Load the rear axle with it on jackstands (the jackstands shown don’t quite touch the chassis in this photo) to set pinion angle. Remember that for vibration-free operation, pinion angle is the exact opposite of the transmission output angle. So if the transmission points down 3 degrees, point the pinion up 3. Forget the pinion-down thing; that’s to counter axle wrap in leaf-sprung drag cars.
