Center caps on factory alloy wheels

I am just about ready to get some factory alloy wheels and i have manual locking hubs in the front of my truck. Is there a special kind of center cap for manual hubs or would i just not use any center caps? The reason i ask is because my aunt has just about the same truck as me and it looks like there could be a center cap on the front of her wheels but i have never seen them on the web. P.s. These are the wheels i am talking about.

 

I have the same wheels. I just buy the normal center caps and cut out the center of the caps with a dremel so that it fits over the locking hub. Ill try to grab a pic of mine.

 

Toyota sells the center cap for the front that already has a hole made to work with the manual locking hubs, that is what I have.
