My speedo doesn't work so I checked over my speedo cable. Was fine at the tranny. Unplugged it from the speedo, there was a small ring on the end of it that was broken. Plugged it back in and kinda wiggled it and the needle did jump a little. I figure I need a new cable. Probably looking at getting one from Napa or Advance. What length do I need, and is there anything special I need to look out for? Appreciate it guys
