Hello, I recently purchased a 67 gto with the rally guage cluster. The one time I drove the car the speedometer did work. The former owner said as he was delivering the car to me the speedometer needle was jumping around and was making noise. Now the orange needle is missing and It is not sitting in the lower part of the speedometer. My question is whats the correct fix and how do I get the speedometer out of the car. May be a good time to replace the cloudy plastic lens covers on all the guages. Thanks.
Tom.
