Help w/gauges in 66 mustang

I bought a 1966 ford mustang from a guy who had some gauges put in under the dash. I am trying to figure out why the other ones dont work. I want to see if i can get them working again. The temp. gauge goes all the way over when you turn the key. the fuel moves a little but the other ones dont work. Can someone tell how and if they can be fixed

Thanks, convertedchevyman

well, if the speedometer isn't working, likely the speedo cable isn't attached, take the bezel off and you can inspect the gauges.

They're not expensive to replace at www.mustangsunlimited.com
