Davidson Rims, Any Locking Center Caps?
 

I just got a set of Harley Davidson Rims for my Expedition in 20, they look great!!

Only problem is I live in a Ghettotastic neighborhood, I got my Expy for 2 days and my factory 17 centers were taken. I saw alot of the newer chromes come with locking or screw on center caps.
Is there any for the Davidson rims, or at the very least an after market kit?

Thanks in advance
