Factory 340 leaf springs, which is right & left?

Looking it up in the factory part book shows part # 3549 059 both sides, no right or left ?
I know that the part # and the # on the spring are not the same, a lot of cars had right and left springs, the right sometime had more leafs than the left or had a 1/2 leaf. My AAR had the same right and left.

I took these off of my car a long time ago and put some S/S (I believe that's what they were) springs on it to jack it up. I sold these to a friend and he noticed the different p/ns and asked which side was which.. Both have 6 leaves.
