I have the same issue here. Can you take the actual cable out of the case and just replace that? I have done that a couple of times, and it always seemed to work.
Hi Jim, sorry it's been so late getting back at you about the speedo cable as it turned out it was stretched out and broken where it enters the spindle so when I measured it out it was like over 100 inches, after all said and done ordering the wrong cables it came out to be the one piece replacement cable from a super beetle. So thanks for all the help and advise I sure need it !! Doug in WI.
