Eagle Alloy Center Caps Where Can I Find A Set Of Center Cap Locks For Eagle Alloy Rims?

Where can i find a set of center cap locks for eagle alloy rims? - eagle alloy center caps

I bought a set of alloy wheels Eagle for my '83 Blazer, but we only had 2 center cap locks, the Caps in the middle to prevent it. I checked the alloy eagle website, but not the case. Can anyone help?
