Replace your Corvettes broken speedometer cables with this improved replacement unit. This is the 1977-1982 Lower Speedometer Cable that connects the cruise transducer to the transmission.
Tech Note: This cable is equivalent to GM recommended replacement #6480549 and is a longer design to eliminate the restrictive short 90* bend at the transmission connector. Be sure to check your cruise control transducer, hook cable to cordless drill and make sure the transducer is not seized up and non functioning.
