Mancini xhd leaf spring question

Damn, I think it would have been easier to call Mancini Racing for the answer... Anyway, MRE 1981 is for the Drivers/Left side and the other one, well...it goes on the other side. Also, it is the Passenger side/right side that has the spring with more leafs/bias because of engine torque not the drivers side because of a fat *** driver.
