nope...someone hasnt done there homework
the actual struts when the car was new had different valving if the car had F41 or FE2...
the front springs are different as well
in the Bonneville the F41 was never available with the ELC, but in the Buick'* it could have been optioned with ELC...
WHY would you want to controll the springs differently?? that really makes no sense as the car sould have the same amt of air on both sides... adding air to both sides at a different time is only asking for problems
