1 tooth larger is a 3% change in mph (adjusts it down)

I have an extra one around somewhere. I believe its a 28t or 32t

It should get it closer than it is though. At 80 on his speedo he's really actually only doing 65. Dependent on what gear is in there now it may fully correct it.

Really? Thats odd that it is that far off, and I mean that the actual speed is that much lower than speedo... I have calculated that my truck with R150 trans, 4.10 gears, and 35's is 12-15% off. At 65 on my speedo, I am actually doing almost 75.

BTW is a gear with different number of teeth something you can get at the dealership?

Marlin crawler sells the gears. When I cared about fixing mine nate looked but the one he had was the wrong tooth count.

Bouncing needle is a sign that the speedo cable is going bad. Some lubrication may help it.
