Please see the picture of the engine flywheels with gears to help select the driven gear with the correct number of teeth for your Cox car.
This sale is for the 34 tooth gear; please see my other sale if you need the 36 tooth gear.
These are 3D printed nylon driven gears for the old Cox direct drive tether cars such as the Corvette, Buick, Chaparral, etc. I have tested this gear myself and it performed very well through 10 full tanks running the car on a tether; the gear showed no wear after testing. The last picture is the gear I used for testing; it may be a little dirty after use, but it worked just as well as the originals! The hexagon center of the gear may need to be slightly enlarged with a small file or emery board to fit over the hub on the wheel.
This is a video of a test run with these exact gears:
