Rear Brake Rotor Size?

[Ckhris]

Im looking at getting new rotors and pads from Brake Stop and it is asking me if the rears are 336 or 350mm. Im sure someone here has ran into this before.
I have looked my rotors up on ford parts with my vin but it did not give me a size

I asked Copilot: The rear brake rotor size for a Gen 3 Ford Raptor is typically 336mm (13.4 inches) in diameter. However, if your Raptor has the Heavy Duty Payload Package (HDPP) or Max Tow Package, it may come with 350mm (13.8 inches) rotors.

Given you cannot spec HDPP/Max Tow packages on a Raptor, it would seem you have 336mm. Can you not go measure them with a ruler?
