Mopar SS leaf springs

All the footage I see of Mopars launching ,the left front tire pulls up at a minimum, now Herb Mcandlesse's modified Demon did a wheel stand, but Im talking about you and me strip built a bodies the left front comes up, which would mean the right rear is digging in and taking all the weight...so which SS spring goes on the right rear?

THe SS spring that has more arch. But they are labeled R and L
