You can probably get the number from GM Parts Direct's website.

I recently went through this too. There does not appear to be a correct size gear available, certainly not in the aftermarket. The only soulution that I found was to replace the entire assembly. The best price I found was around $41 from Dal Chevrolet in FL. BTW, the part # is: 1103868.

Then we could go to Comp Cams, Crane or many other vendors for a replacement gear. Comp is tooling up to give is an Polymer alternative as is Crane.
