Yeah, I'm beginning to think I just got lucky or would like to believe that I actually realized the different lengths as I was installing the cable since routing towards the rear is along the left side until the cable splits towards each caliper. So, it makes sense the right side needs to be longer. In addition, the Wilkinson Pantera parts catalog lists different part numbers for the RH and LH cable housing. This is the only other photo I have of the cable when still in its wrapper. Hard to tell, but the side of the cable that crosses under? the other side appears it might be a little shorter. Regardless, more Pantera trivia to fill the few open spaces left in my brain.
