This is the complete gear shift cable, casing, boot, hump seal with all the right ends and right length for the Auto T350 & T400 for most all US GM vehicles from 69 to 81, all Camaro (except 69-72) all 70+ Firebird TA, Impala, Bonneville, GP, Catalina, Granville, Nova etc.
THE LENGTH is 770mm hole to hole..
This is the correct cable assembly if you have the original floor shifter.
There is also another cable for around 68-69 Firebird.. and anther for 68-72 Camaro models listed.... distinctively different floor seals is an easy way to tell.
* AS A SIDE NOTE.. make sure your engine to frame is earthed.. otherwise your only earth will be though the cable.. and you'll fry the cable quicksmart.. .. sometimes happens during restorations / engine swaps etc.. not vitally import note but just keep it in the back of your mind someplace....
