Thanks for the replies! Yes, I realize it’s not a U.S.A. gauge, truck was imported from Africa. Roverp480, I think you are correct - upon closer inspection it appears the back connection has been sheared off - when I look under magnification it looks to have been cut off (see zoomed in pic). I like your idea of a hose clamp - that may hold things in place. I will test run with a hose clamp before putting everything back together. If successful, I have to order a new 20 tooth gear for inside the speedo - $35 shipped for a plastic gear that is smaller than my pinky fingernail! Thanks again.
