I have started to put back together a 66 Dart that I tore down about 20 years ago. I started to install the torsion bars, and went online to see how they need to be clocked. Now it sounds like there is a left and a right, and also a front and rear to each bar. Any way to tell which is which? Markings on the ends are hardly legible, but one appears to have the number 625, the other may have 445 on it with a circle around the center 4. Any help is appreciated--thanks!
