Speedometer on my '77 reads fine up to around 40, then bounces wildly at higher speeds. Is the problem in the cable or the instrument cluster? Info on the fix would be helpful.
Usually the cable, pull it out and lube it good.
Yup, cable replace is probably in order. I need to change the speedo out anyway. I've gone from P235 75 15's to 33 10.50's. Where can I find the chart to know what speedo to order?

The number of teeth is labeled on the collar of the pointed end, "17T", "19T", and so on. Also they are color coded.About the calculating thing, how do you find the right gear when you don't know what you started with? A few years ago I melted/stripped my spedo gear and went to the Ford dealer for a new one. They didn't know the size and couldn't match from what was left of the old one so I just picked a number and went with it.

I think that part was melted on mine. I think the one I had was dark red.
