ok so im redoing my suspension on my charger but i must have ordered kyb's for a omni not a charger. the omni shock is longer and the perch on the shock itself is also in a different location. my question is can i use a omni rear spring in the charger since the spring from the charger is completly different also without rasing the rear of the car to much and will the rear shock have any ill effects or should i just get the right strut for the car?
