Saab: 1994 900 convert. (1993 parts), speedometer gear, speedometer cable

Question
Hey Jerry I have another question,  My  speed/odometer has stopped working.  It was having problems with it going up and down erratically and now it is gone.  What is involved and what parts will I need  to replace to fix it?

Answer
David:
 If both speedometer AND odometer functions have failed, then the likely cause is either the internal speedometer cable running from transmission to speedometer head, OR a nylon speedometer gear located in the transmission itself, accessible from under the car. An internet site "foreigncarpartsonline" usually stocks the cable. Of course its always possible that the "clock" has failed internally, but that is less likely.
