Speedometer

[GL Dave]

I'm driving on the freeway the other day in my 72, the needle on the speedo dropped, and my speedo just went out. I've been trying to fix it. All of my connections are fine (I think), there aren't any fuses blown, and as far as I can tell, the speedo cable seems to be properly in place (I think).

Would the cable need to be replaced? is there anything that might not be attached properly? Is there anything else I should check?

Thanks alot
