This issue may be in the drive mech in the speed o. Mine was shot when the guy restored my cluster. Told me this issue on old speed O. is common. Have you replaced the cable coming to the speed o from the trans. The drive in the speed o is complicated to say the least. May have to take it to a company that can fix it for you. Those parts are getting hard to find. Wish you the best with it. Russ.

AZ Desert,
I use Red Line Gauges in California if you can't find anyone down there. The local speedo shop said two of mine were junk but Red Line fixed both. Not cheap though.

So here is what I have been told. The speaker magnet is the problem. The magnet in the tach is small and the speaker over power's that one. I have a dual speaker in the dash. Was told it will read right once I start the car.

Have tried to fix a few and they just fell apart in side. Worn beyond repair. Good that you could fix it. Now you can get the car on the road.
