bought a 89 sunbord gt vert w/turbo last weekend. no speedo, tach or turbo boost working. bought listed speedo cable, tore dash apart and guess what? right! no cable. (don't know they can have a listing for something that is not there). now i am trying to find out what years interchange and if anyone has one for sale. taking it to a speedo shop next week but, am expecting the worst. thanks in advance.
