Please help me get the CORRECT speedo cable for my 1988 B150 van. The cable that the books list from Autozone, Parks Auto, o'Reilly's, is the wrong cable. The fittings are the wrong size. The end of the cable that attaches to the speed sensor is threaded on the outside, which is correct, but the threaded part is much too large for the vss nut to screw onto. The other end of the cable that attaches to the speedometer gear in the tranny is a nut, which is also correct, but the nut is much too small to screw onto the gear. I'm at a loss here. Please help.
