Stop in for a cup of coffee

So I just got a nasty gram from Summit. I ordered a pair of SS springs for the Demon, they have left and right. They sent me one spring and I figured other is on back order. No worries right? They just sent refund and no spring in sight? WTF good is one SS spring?

Is there one more spring on one side or a higher spring rate? Just asking because I sent mine to powdercoat and the pads melted out, was reading some guys order the same spring both sides because their cars sit more level, was considering that.
