I guess your thread where I posted an answer to your questions was deleted.
Here is what was on that thread:
I would venture to say your wheels are 4-bolt mangels. 4 -bolt wheels typically have 8 slots/holes and the hubcap sits on top of the wheel surface.
5-bolts wheels (commonly referred to as wide-5's) have 10 slots/holes and the hubcap sits more flushed with the wheel surface.
There are many sources for these hubcaps, but try this link for more info...
I hope you find this information useful. Tough crowd on SOC.
