Think I've got enough pieces now to swap parts and get a speedometer that works. Odometer is OK. There sure are small, delicate, intricate parts in that device. In order to do this, the challenge is to remove the speedometer needle. Without damage. I think it just lightly presses onto a tiny shaft. It has also been on there a while. Anybody done this on an old car? Somehow get under there and pry it up, don't scratch the surface of the gauge. Non specific instructions say "be careful" and patient. One suggestion was use a fork. The needle is very thin aluminum. Not something you do often, if at all. The picture shows what looks like a brass bushing on the needle going onto the shaft. Helpful comments, suggestions, advice welcome. Will report on progress, or a pile of parts. Thanks.
