There is a unit on the speedometer cable with a wire coming out of it. part # is 3458494 i thought it might be a mph to kph device but canada never changed to metric till 77. Any ideas what this unit is ?

Good answer , the only problem there is that the dash does not have any lights or individual lights to indicate a "service engine " mode . I will check again and make sure . BTW would this be a rare option ? the 30 or so A bods that my cuz has parted out never had this unit .

Belevedere had one on it from the factory with 4.56 gears and stock 14 inch rims and tires Can you post a pictureof it? If so do that and I'll tell you if it look like thoen I had Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
