Did I do something stupid?

I have a 69 340 swinger 4-speed. Around ten years ago I put on Mopar performance leaf springs. The other day I was looking it over and I noticed that the right side was soggy. After looking under it, I saw the two leaf springs are different. The left side has more leafs. Are these backwards?
It sounds like it, yes. If they are SS springs, the car should favor the driver's side in the rear so that when it launches, the car will straighten up from the torque of the drive train. If you can see the part numbers, even is for one side, odd is for the other......I just cannot remember which is which. I am sure someone will tell us shortly.
