This is a factory style replacement throttle cable for your 1979-1985 Mustang 5.0L 5-speed. This cable is specific to a manual transmission and will bolt directly in place of your existing cable with no modifications needed. The overall cable length is 23 inches.
This is a throttle cable/accelerator cable, not a throttle valve cable!
I bought this cable a year ago to replace the factory cable on my 1982 Mustang GT. It is very poor quality, binds very badly and is too long for the application. It failed today and I replaced it with a Lokar throttle cable. It is much nicer looking, much smoother and cheaper. I expected much better from LMR as their products are usually very good quality.
