Well, I managed to fix the clicking noise... All I had to do was break the damned thing and no more clicking !!!
So now I'm looking at replacing it... I need to pull it and measure it. I called Hall Pantera, they measured the one for an early Pantera and said it was roughly 149.5 inches... The ends should be the same since its going from a -1 ZF to a Veglia speedo... I just need to get mine out and take some measurements.
Worst case I send the ends out and have one custom made.
No good deed goes unpunished!
