I know that 83-8 had them but I'm not sure about later. I need one for my car as mine is melted. I think when it was ran with just the headers it meted it, but I'm unsure. If possable I would need the whole speedo cable, from the back of the cluster all the way to the tranks. I'm not sure if the "gears" are different for the rear end combo's but my stock gears are good. If someone has one, let me know.
I'm still wondering if the Stang cable is the same.
I'm willing to take a chance. This is one of the last obsticales I have left ( MC/Booster, re-running fuel lines, and a good tune on the carb)
I have one from an 83 TC if it will work for you. $10 shipped.
See, I duno if it will work. I'm willing to get creative and try though. I'll let ya know firday
Call Autozone and ask for the part number to an '84 T-Bird and an '84 Mustang.
I will tomorow. I'll also try to cross reference the 5.0 and the 2.3 cables

The Motormite (Part# CA3011) says it fits any 79-95 Mustang and 80-88 Thunderbird as well a load of other cars.
I can also see about getting the one off the '83 3.8 @ The yard, But it might also be burned since thats the side the spark plug wire was melted and they charge 7.50.
