Trunk lid torsion rods install

[XracerX]

I removed the 2 torsion rods back in 1988 for super large JBL 6x9's and when I switched back over to 4x10's I may have mixed up which one goes left and which one goes right. At the first setting is where I have them but I am not sure I installed them to the correct sides. I might have swapped them to get them on easier and so I have been propping the trunk up with a stick since he early 90's. Is there a way to distinguish the placement of the 2 rods or maybe a part number stamped on them?

20569468 is the right with the squared end
20569471 is the left with the squared end
