US 280i Rear Springs? Help!

[MIKAG]

I have a 1987 US model 280i in excellent running condition with a slight exception. The springs on the vehicle are in very poor condition I have secured front springs, however, I do not know what type of rear springs are appropriate for this model. Any help would be greatly appreciated. Thank You.
