Speedometer Cable

RedFish is correct about the 2 piece cable. The 1972 Demon Calif. car had the Nox emission pkg. The emissions switch is between the 2 cables. You can probably read more about it in the 1972 factory service manual. The easy solution is to remove the 2 piece cable and replace it with a 1 piece cable 3592360 which is 62 inches long. 80 inch cable found in parts stores is a universal fit for many applications and is to long for A bodies. Most of the Mopar online stores stock the 62 inch cable. If you most have the 2 piece cable,go to Ebay and enter this number 2985875. Hope this helps.
