You realise that the right side spring will raise the right rear of the car about an 1 1/2 higher than the left side?
I ordered the left and right (same part numbers you posted) thru my Chrysler dealer out here and realised the expensive way that the car doesn't sit level with the left and right springs. I wound up ordering another left spring (and they don't accept returns so I've got a new right spring collecting dust).
