    I'm in the process of making an overlay for a CT90 Nippon Denso speedometer. Does anyone have a picture of a pristine speedometer by that manufacturer? I want to verify the color of the shift sweeps. Mine is faded and I would like to get the color as close as possible.

    I guess "update" means pay ransom?

    Yes and look at the cable providers too. They raise rates constantly using "packages" as a means to justify it. I'm trying to get my wife to agree to drop it.

    Wifey's been tryin to get ME to drop it too. I'm pretty much ready now, but we will probably keep the internet service with them, for now. They are gonna get us one way or the other tho. We can fight, but we're gonna lose, IMO. When the government is working with THEM, to steal money from US...well, we're just gonna get screwed.

    Looking at the bright side, now I know where to invest my millions.

    I found a speedometer online and tried to match the color of the shift sweeps. This is what I came up with.

    One of the few I've seen has those sweeps colored a dark orange, so that's what I went with.

    My non Denso looks very similar in color. Good choice

    From what I've seen, Nippon Seiki's also had that coloring. One challenge that I see, if you want to roll back the mileage, is that the barrel is clinched in place and not easily removed.

    I think your project is a success I didn’t think about the mileage barrel. I think BC17? did a thread on how to restore the barrel a few years ago. Thanks for giving some of us hope when it comes to our worn out speedometers.

    Taking these speedos down to the bare minimum reveals some toasted rubber grommets used to keep light rays straying from their intended target, the jewel lens. They are placed around the metal tubes that contain the telltale lights for high beam indicators, neutral indicator, etc. I was wondering what I could use as a substitute for the originals and decided on 7/8" heat shrink tubing. I placed a piece of 1/2" PVC tube on top of the metal tube and slid on a 7/8" long piece of shrink tubing, with about 5/16" protruding and surrounding the PVC tube. I used a heat gun to reduce the tubing and then remove the PVC tube. A drop of super glue keeps everything in place. You want to make sure that the heat shrink tubing does not interfere with mounting the face plate and the 5/16" dimension worked for me.
