can anyone tell me where i can find the missing part of the center cap?

 

you are missing the collar and center cap. i have one cap and one center cap.

 

you wouldnt happen to have pictures of just the parts im missing?

 

you are missing the hexagon shaped cap(shown on top left pic) and the plastic threaded collar (shown in bottom right pic) the key hole shown in far right pic is hidden under a logo chip(shown in bottom left pic) that clips onto the top of the hexagon shaped center cap("hex cap" for short) there is a key that opens and closes this particular set. not all ewings came w/ this function of security.

the caps i possess are a non locking kind (plastic) and the collar is as well plastic.

 

r.wright do you still have the collars for the locking metal center caps? Looking to buy asap!
