Most accurate Speedo cable 69 428 with C6

Thanks Royce. You’re right, speedo cable was passenger side of the 4 speed. Very close to right exhaust pipe. Still working on getting the cable “collar?” fitting out. Used WCCC speedo gear calculator with tire diameter, actual speed compared to speedometer speed, etc, Said I should use 15 teeth gear, but they only have 16 teeth. Right again that 16 teeth is lowest available anywhere I searched. Supposed to be approx 2 mph off actual speed. Appreciate it.

You must have the 4 speed version of the speedo gear because otherwise it would strip immediately. In any case there are gears available to suit your needs.

Thank you Royce. I’m tracking one down.
