Hello to all. I have an 84 Eldorado with a cable driven speedometer. I found a digital speedometer for sale and was wondering if they can be swapped. I doubt it because the digital should run off a sensor and the cable driven, is well, cable driven. Or were the digital just the read out and the thing works off the cable. Anyway, I don't have a clue and thought I would address this to the forum. Looking to hear back from some one. Thanks. Bigbird_55.
