Vex Gear Sizes

Hi!
I am trying to fix a broken animated track thing and I can use the Vex Chain perfectly, but the main sprocket (?) gear I have has teeth way too big for the smaller Vex Chain.

Can anyone tell me if Vex makes a sprocket gear for their Vex Chain that measures exactly 3.25" across (from tip of one tooth across to tip of opposite tooth.) The gear I have is .25 wide.

Thanks to anyone who can help.

Unfortuntely we are not aware of that gear. If you are able, you might try to draw it yourself and have one 3D printed?
