snapped 393 internal gear

i have a 393 motor that inside the green side of the casing the last ear to come out, the gear that transfers the motion from the green side to the black side has snapped in half (not two halves of a gear, but two new gears) are there any replacements for this? or do i simply have to buy a new motor?

Vex sells replacement 393 gears:

What most teams do when motors break is keep their broken motors and wait until a different motor breaks in a different way, then combine parts from the two into one functional motor.

yea, i saw that but those are speed and strength gears for the black covered part of the motor our gear is broke on the green side. but i think were simply going to buy a new motor
