gobblert, the gear drives aren't very expensive, it's the speedo itself that usually runs the big money. If you would settle for a less than cherry speedo, then maybe you could get real close to your $60, but more than likely $80 to $100 though. The 90/110/185/200/ speedo drives kits were really cheap at one time, but have even pretty much dried up. I think I still have a nos speedo drive kit like that and a less than cherry speedo. I never tested the speedo to see if it worked though when I got it. It's dented and has some rust on it, but the lens is unbroken and the speedo is still attached. I've seen people use worse speedos. If you could find someone who would remove the lens and take the dent out of the shell and repaint it, then it should be ok.
