1968 Mustang Speedometer needle "bottomed out"
While replacing bulbs behind the instrument cluster, I disconnected the speedometer cable. When I put reconnected it, the needle is what I would call "bottomed out". It is resting at almost the 6 o'clock position and now it is reading about 20mph slower than actual speed. It was calibrated perfectly before I did this....
How do I get the needle to rest at zero? FYI there is no pin for the needle to rest on.
