Torsion bars

Question, does it matter which direction the torsion bar goes in? L, left side / R, right side. Does that letter R/L need to be facing to the front or rear? I know, dumb question, but a friend is trying to tell me that the letter needs to face the rear. I do not believe that it matters.

With Chrysler odd numbers are on the drivers side, even numbers on the passenger side. The big block bars are 894 and 895, so 894 goes on the passenger side...
