67 BJ8. Years ago my speedo needle was just thrashing around so I just disconnected it. A few years later I decided to send it off to be checked, sent to MOMA. I installed new elbow, new washer, and I had a NOS speedo cable. When I got it back nothing worked. Talk to MOMA and they said to send it back. They said it worked perfect right out of the box, but they would check it again. When I got it back the odometer worked but the speedo still didn't, so I am asking, is there something I'm doing wrong?
