Perhaps a very dumb question . . . is there a top and bottom to rear coils?

[One Big Rush]

My 68 has CCP 4" lowering coils. It sits a bit unlevel from side to side.

I am about to go even lower and have the parts bought. While getting my game plan together, I noticed that the logo on the coils is upright and near the top of the truck on one side and upside down and on the bottom on the other side of the truck. Is there a top and bottom to the springs in how the little pig tail is designed to fit?

Just curious as it would be an easy change while I am adding 1" drop blocks and shock re- locators.

Thanks,
