I think I made a mistake ordering a 1717/1Y 1500kv motor

I ordered from the motor clearance sale on CC's website. Looks like I got the heli version of the motor. The rotor is larger than 5mm. I'm afraid I made a mistake or hasty purchase. Hoping Patrick or someone from CC will respond.

What do I do now? Can I send it back and trade it for the car version? Do I need to order a 5mm rotor kit for it instead?

I want to run this in my D8Te converted truggy on 6S. I have the EliteRC motor mount for it, and the motor seems to fit despite how much larger it is in diameter. Not sure what pinion options I'll have though.

The pic is side by side with a 2200kv motor.
