We have a 72 scamp with 3 hole adjustable rear shackles and s.s springs,what affect will moving the position have on the vehicle.I'm guessing that moving to a lower hole will raise rear of vehicle.Also wondering if this will change the load on the spring in a different position ie moving the position to top hole will increase spring rate or decrease.Car has on side in middle and one side in top but will launch straight on the strip.
Thanks
